Questions about Dia INN
What time is check-in and check-out at Dia INN?
Check-in is from 3:00 PM. Check-out is by 10:00 AM. If you're arriving late, tell us and we'll ask the property to hold the room.
Does Dia INN allow pets?
No — the property states that pets are not allowed.
Is there parking at Dia INN?
Yes — the property states that parking on site is free. Whether a space can be reserved in advance varies, so we check it against your dates.
Does Dia INN have Wi-Fi?
Yes — internet access is listed among the property's facilities.
Does Dia INN 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 Dia INN?
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.
