Rooms were dirty, pull out couch was clearly not changed or cleaned. Smoke detector was actually pulled out of ceiling and missing. Crazy when we all actually had to leave building or room up main floor due to fire alarms going off. They could have mentioned when we booked, no liquor license and could not serve in restaurant or hotel. Just run down and needs more help and upgrades but kids had fun, so we made best of it.

Liked: Cleanliness, property conditions & facilities, room comfort
The facility was fine. Lobby was very ordinary for a "Grand" motel, more geared to their waterpark. Only 11 rooms that night so breakfast was on a table in the lobby. Pastries, fruit, cheese, granola bars, orange & apple juice, reg coffee. VERY limited gluten free options, fruit & cheese. My husband can't have caffeine so no hot drink for him. We went down the road to a Kwik Trip.
