What Is Marriott St. Louis Airport Parking and Where Is It Located?

Marriott St. Louis Airport parking is a designated self-park lot attached to the Marriott St. Louis Airport hotel, located at 10700 Pear Tree Lane, St. Louis, MO 63134. The hotel sits just off Interstate 70, which is the main highway into St. Louis Lambert International Airport. From I-70, take Exit 235C onto Cypress Road and follow signs toward the airport hotel corridor.

The lot is uncovered and outdoors, with a gated entry and exit. You park your own vehicle, check in at the hotel front desk, and wait for the shuttle. The 24/7 front desk staff can assist with check-in at any hour, which matters for red-eye or early-morning flights. Natural Bridge Road and Pear Tree Lane form the main airport hotel corridor near STL, and the Marriott sits along this stretch alongside several other airport hotels.

St. Louis Lambert International Airport — officially St. Louis Lambert International Airport, operated by the St. Louis Airport Authority — is 14 miles northwest of downtown St. Louis via I-70. The Marriott is close to the airport perimeter, making shuttle rides to the terminals relatively quick.

How Much Does Marriott STL Airport Parking Cost?

Based on current Triply rates, Marriott St. Louis Airport parking costs $10.45/day (verified October 2026). That is a flat daily rate for uncovered self-park in the gated hotel lot. The free 24/7 airport shuttle is included — you do not pay extra for it.

To understand the value, compare that against on-airport Super Park rates, which took effect July 1, 2026, per the St. Louis Airport Authority:

Parking at the Marriott for a 7-day trip costs roughly $73.15, compared to $217 for the Terminal 1 Garage over the same period — a saving of over $143, or about 66% less, based on current published Super Park rates. For a full breakdown of every STL lot, see our STL Airport Parking Rates 2026 comparison.

The Marriott lot is one of the pricier off-site options — only the Crowne Plaza Airport ($10.49/day) costs more among the six off-site lots bookable on Triply. The lower-priced lots like Quality Inn ($6.50/day) and Renaissance St. Louis Airport ($6.77/day) offer bigger savings, but with more limited shuttle hours. If a true 24/7 shuttle matters to you, the Marriott's $10.45/day rate is competitive for that level of service.

How Does the Marriott STL Parking Shuttle Work?

The Marriott St. Louis Airport shuttle runs every 20 minutes, 24 hours a day, 7 days a week — including holidays and overnight. This is one of the more frequent off-site shuttle schedules at STL, matched only by The Parking Spot 3, which runs continuously.

Here is how the shuttle process works, step by step:

1. Drive to the Marriott St. Louis Airport at 10700 Pear Tree Lane. Enter the gated lot and park your vehicle.
2. Check in at the hotel front desk with your reservation confirmation. The 24/7 front desk staff will note your vehicle and provide shuttle details.
3. Wait for the shuttle at the designated pickup area outside the hotel lobby. The shuttle departs every 20 minutes.
4. The shuttle drops you at the STL terminal. The Marriott shuttle serves both Terminal 1 and Terminal 2 at St. Louis Lambert International Airport.
5. On your return, call (314) 423-9700 after collecting your luggage. The shuttle will meet you at the designated pickup door at the terminal.

The airport recommends arriving at least 30 extra minutes early to account for parking and shuttle time. With a 20-minute shuttle frequency and a short ride, budgeting 30–40 minutes from the Marriott lot to your departure gate is a reasonable estimate. Always review TSA security screening guidelines before your trip, since security lines vary by time of day and add to your overall timing.

Compared to the on-airport Super Park shuttles — which serve Lots A through E every 8–15 minutes with live tracking via Passio GO — the Marriott's 20-minute interval is slightly less frequent. However, the Marriott shuttle is free and runs around the clock, unlike some budget off-site options with restricted hours.

How to Reserve Your Parking Spot at Marriott St. Louis Airport

Reserving in advance is strongly recommended, especially around holidays and summer travel peaks. Walk-ins may be available, but the gated lot has a finite number of spaces and popular dates fill quickly.

To book Marriott St. Louis Airport parking through Triply:

1. Go to Triply's STL airport parking search.
2. Enter your travel dates and select the Marriott St. Louis Airport from the results.
3. Confirm your reservation — the rate of $10.45/day is locked in at booking.
4. Bring your confirmation to the hotel front desk on the day you depart.

Booking through Triply also lets you compare the Marriott side by side against all six off-site STL lots.

Is Marriott St. Louis Airport Parking Safe and Secure?

The Marriott lot is a gated facility, meaning entry and exit require authorization. This provides a basic perimeter barrier against unauthorized access. The lot sits on hotel property, which typically means security cameras are present and hotel staff are on-site around the clock. The Marriott's 24/7 front desk provides continuous on-site human presence, which is a meaningful security factor for overnight parking.

That said, the lot is uncovered and outdoors. St. Louis weather can include hail, ice storms, and high summer heat. If you are parking a newer or high-value vehicle, consider whether an uncovered lot suits you. The Parking Spot 3 ($9.74/day) offers covered garage parking and is a nearby alternative if weather protection is a priority.

No independent security audit data is publicly available for the Marriott lot specifically. For the most current information on security features — such as camera coverage, overnight patrols, or lighting — contact the hotel directly at (314) 423-9700 before booking.

Marriott STL Parking vs. Other STL Airport Parking Options: Which Is Best?

The right lot depends on what you value most: price, convenience, shuttle hours, or vehicle protection. Here is a direct comparison of Marriott St. Louis Airport parking against the closest alternatives:

• Marriott St. Louis Airport ($10.45/day): Gated, uncovered, 24/7 shuttle every 20 min. Best for travelers who need a reliable around-the-clock shuttle and prefer hotel-based security.
• Crowne Plaza Airport ($10.49/day): Nearly identical price, also gated and uncovered. Shuttle runs every 30 min 24/7 — slightly less frequent than the Marriott. Has on-site security cameras listed as an amenity.
• The Parking Spot 3 ($9.74/day): Dedicated parking facility with covered and uncovered spaces. Shuttle runs continuously 24/7 and picks you up at your car. Slightly cheaper and offers covered parking — a strong alternative if weather protection matters.
• Hilton St. Louis Airport ($8.39/day): Cheaper than the Marriott, also 24/7 shuttle (every 30 min). Accepts oversized vehicles at no extra cost and has EV charging — better value if you drive a large vehicle or EV.
• Renaissance St. Louis Airport ($6.77/day): Cheapest 24/7-capable option, though overnight shuttle is on demand (call ahead). Saves about $26 per week compared to the Marriott.
• Lot D — On-Airport ($11/day): Only $0.55/day more than the Marriott, with a free Super Park shuttle every 8–15 min and live tracking. If convenience to terminals is the priority, Lot D competes closely on price.

For travelers flying Southwest, British Airways, or Lufthansa out of Terminal 2, the Marriott's 24/7 shuttle frequency is a real advantage over lots with restricted hours. Travelers on Terminal 1 airlines — American, Delta, United, Alaska, and others — will find the Marriott shuttle serves them equally well.

What to Know Before You Park: Accessibility, Oversized Vehicles, and Policies

A few practical details to know before you drive to the Marriott lot:

• Accessible parking: Hotel properties are required to provide accessible spaces by law. Contact the Marriott directly at (314) 423-9700 to confirm the number of accessible spaces and whether the shuttle vehicle is ADA-compliant before booking.
• Oversized vehicles: The Marriott lot is listed as an uncovered, gated self-park facility. If you are driving a full-size van, truck, or large SUV, call ahead to confirm clearance and availability. The Hilton St. Louis Airport explicitly accepts oversized vehicles at no extra cost — a verified alternative if your vehicle is large.
• Payment: Booking through Triply locks in your rate at reservation. For any on-site payment questions, contact the Marriott at (314) 423-9700.
• Cancellation: Cancellation policies vary by booking date and provider. Check the specific terms at checkout when booking through Triply.
• Early morning and late-night flights: The Marriott's 24/7 shuttle is one of its strongest features. Unlike the Quality Inn (which stops shuttle service at 11 PM) or the Renaissance (which switches to on-demand overnight), the Marriott runs on a fixed 20-minute schedule all night. If your flight departs at 5 AM or arrives at 2 AM, you will not need to call ahead for the outbound shuttle.
• TSA PreCheck: If you have TSA PreCheck, security at STL moves significantly faster. Factor that into your timing — PreCheck lanes typically clear in under 10 minutes, which means your 30-minute shuttle buffer may be more than enough.

One more thing to be aware of: St. Louis Lambert International Airport is in the middle of a major long-term construction program. A new consolidated terminal — estimated at ~$3 billion and targeting up to 62 gates — is in design as of spring 2026, with a groundbreaking targeted for 2027 and opening around 2032, according to First Alert 4's April 2026 reporting. No major parking closures are announced for 2026, and off-site hotel lots like the Marriott will not be directly affected. Still, verify current terminal assignments at flystl.com before each trip, as airline shifts are possible from 2027 onward.
