ThomasUnited StatesThe place was gorgeous but they wouldn’t let me pay with my Chime card……. Very disappointing because it’s no different than any other banking debit card.

- The pet fee and any size limit, which is where these bookings usually come apart.
- Whether there is room for a pickup, a trailer or a van, not just a car.

Questions about Aloft by Marriott St. Louis Cortex
What time is check-in and check-out at Aloft by Marriott St. Louis Cortex?
Check-in is from 4:00 PM. Check-out is by 12:00 PM. If you're arriving late, tell us and we'll ask the property to hold the room.
Does Aloft by Marriott St. Louis Cortex allow pets?
No — the property states that pets are not allowed.
Is there parking at Aloft by Marriott St. Louis Cortex?
Yes — parking is available on site at a charge the property sets. We check the rate and whether a space can be reserved against your dates.
Does Aloft by Marriott St. Louis Cortex have a pool?
Yes — a pool is listed among the property's facilities. Seasonal closures are common, so we'll confirm it's open for your dates.

Does Aloft by Marriott St. Louis Cortex have Wi-Fi?
Yes — internet access is listed among the property's facilities.
Can I book a block of rooms at Aloft by Marriott St. Louis Cortex?
The property lists meeting and banquet space, which usually means it handles group business — but how many rooms it will hold at once, for how long, and at what rate are set case by case and are not in any feed. Tell us the dates and the number of rooms and we'll get those terms from the property in writing before anything is charged.
Does Aloft by Marriott St. Louis Cortex have wheelchair accessible rooms?
The property lists step-free or accessible facilities. That flag is the one least able to settle the question: a hotel can carry it and still have a step at the entrance, or a bath rather than a roll-in shower, and it does not say whether the accessible room is free on your dates. Tell us what you need and we'll ask the property directly rather than reading you the flag.
Can I check in late at Aloft by Marriott St. Louis Cortex?
The property lists a front desk staffed 24 hours, so a late arrival should be possible. Standard check-in is from 4:00 PM. Rooms are still released after a cut-off at some properties regardless of the desk hours, so tell us your arrival time and we'll have them hold it.
How do I book Aloft by Marriott St. Louis Cortex?
Put your dates in above and book online, or call (888) 789-8585 and we'll do it for you — including things a booking form can't handle, like a block of rooms, a monthly rate or an invoice for your employer.
