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The rooms are basic, outdated and our carpet was stained.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.

We had our 11 year old grandson with us. We were hoping to use the water park but it seemed like ot was for little kids. We did not use it. I was very happy at check-in that we could get a room overlooking the Mississippi River. I had not requested that on my reservation. All in all we were very happy with our stay. We liked being on the river walk and within walking distance of the National Mississippi River Museum and Aquarium. There is so much to see. We were able to use our admission for 2 days so we could split up our time there.
