Meh!!

Both bathroom and bed linens were dirty. In an attempt to call the front desk, we discovered that the phone in the room didn’t work. Elevator smelled of marijuana. Enjoyed the staff at Tony Roma’s.

Family weekend get away

Hotel overall was good. Hotel was clean. Breakfast was surprisingly really good!!! Arcade and water park was average. Definitely well used and could use some up grades. The one downfall was the smell and amount of chlorine used in the water park. It hit you once you walked into the park. We could only be in there maybe 2 hrs and the kids started to cough so bad almost vomiting and our eyes burned for a couple hrs after getting out.

Fun time

We had a family gathering for the weekend and very much enjoyed the Water Park and overall hotel experience. Our room was comfortable and clean. The water park is a nice size for younger children. Lots of fun was had by all. We would book again.

SO OUTDATED. Way too expensive of a night for how outdated the rooms and water park area are. The main slide and hot tub were not open all hours of the park being open.
