The place is going down hill, wallpaper in the bathroom is peeling, hardly any light in the room, one light did not even work while another flickered, cannot get back into the building from the back door if walking to the riverwalk without having to walk around the building to the front, no benches in the front of the building for people that smoke, building was filthy on the exterior, and for the price for the one night stay was to pricey, staff was nice but at check-in they also had a $50 fee added for some stupid reason, continental breakfast was consisted of liquid eggs, brown and serve sausage, and a few other items, not impressed for the room price stay, stay at you own risk, check out other hotels

Humidity is always a problem in a Waterpark hotel, the bathroom ceiling particularly in our room had seen its better days. Nothing that changed functionality, but it was cosmetically noticeable. Good location, we have stayed here in the past and will stay here again, the kids love it! Breakfast is good too.
