I requested late check-out due to an ordination at the Cathedral of St. Raphael tomorrow morning. I'd like to return to change clothes before my return trip. Front desk would not consider it. Still would appreciate a later check out than 11am. 1 pm if possible for room 503.

It was a decent hotel. Pool area was only open from 4pm-9pm. They had continental breakfast advertised all over but in the morning it was a granola bar or a microwaved breakfast sandwich.

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.
