Liked: Amenities
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.

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.

The bed was really comfy. They accommodated me with the request that I wanted up on the top floor. Great check in. Unfortunately there’s no way to skip around the fact that for an hour and 20 minutes the fire alarm went off at least 11 to 12 times. After walking down the stairs over three times with rheumatoid arthritis I was in quite a bit of pain and just quit going down. The firetrucks didn’t even show up until many many had gone off. The fire alarm was deafening and at a very high decimal so kind of ruined the evening otherwise the visit would’ve been excellent.
