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.
