Ok first the water park…. Part of it is closed which was the big pool and hot tubs. All closed!in the hotel room after showering we could not get the shower to turn off. Maintenance came up and took him an hour to fix it. Also realized after shower that our feet were black from walking on the carpet. It was so dirty in gross we didn’t walk barefoot the rest of the time. So gross!!!

Staff could be just a little friendlier. Check-in shouldn’t be at 4pm if someone is visiting for one night cause now they only have a few hours to spare at the Waterpark. Yes granite you give the visitor

Pool staff were nice. Suggest that check in let people know to bring an ID to the pool if they’d like to get alcoholic drinks. Pool area structures are rusty and look dilapidated.

We choose this hotel for its location on the river walk and its convenience. Friendly staff and reasonable rates are another reason.

It's a pretty basic hotel, but that's all we were looking for. The breakfast was really good! I loved that the riverwalk was right behind the hotel.

The carpets in the halls were pretty grungy. In our bathroom the wallpaper was peeling near the ceiling. The shower curtain rod had been replaced a couple times and there were several holes where the old hardware had been. The paint in the room had been touched up and was a near match we could definitely spot the touch ups. The vent in the bathroom was really dirty. However,.. front desk staff and housekeeping staff were absolutely great! Smiles and kindness were abundant and we would stay again! Regardless of the cosmetic deficiencies!

Everything was pretty dated. The waterpark was rough. Lots of flooring worn and crumbling, rusty play structures. The continental breakfast options were okay, but the plates/bowls were all styrofoam. We weren’t given info on WiFi or checkout procedures, but the staff was very friendly and willing to help.

The rooms are basic, outdated and our carpet was stained. The Waterpark was so rusty and run down it should be condemned.
