Questions about Thames Inn and Marina
What time is check-in and check-out at Thames Inn and Marina?
Check-in is from 3:00 PM. Check-out is by 11:00 AM. If you're arriving late, tell us and we'll ask the property to hold the room.
Does Thames Inn and Marina allow pets?
No — the property states that pets are not allowed.
Is there parking at Thames Inn and Marina?
Parking is listed among the property's facilities. Whether it's free and whether a space can be reserved varies, so we check it against your dates rather than promise it here.
Does Thames Inn and Marina 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 Thames Inn and Marina have Wi-Fi?
Yes — internet access is listed among the property's facilities.
Does Thames Inn and Marina 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.
How do I book Thames Inn and Marina?
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.
