Room was not as clean as previous stays. Restaurant didn't have a liquor license, so that was disappointing to adults. We ordered 2 pizzas for dinner and the second took a very long time; almost an hour with no explanation given by wait staff.

Rooms are super dated. The blanket situation is awful…sheet, thin microfiber blanket and another sheet, but that was ok for us as the thermostat wasn’t working we had it down to 62 and was definitely upper 70-80 degrees in the room. Blinds were ripped, and has a old banquet chair in our room, not the plush one shown in pictures.

The room was clean and surprsingly quiet for the amount of kids. The kids had a blast at the waterpark. The waterpark needs a facelift and some repairs but it appeared they are working on updating parts of it. The breakfast was surprsingly good and exceeded expectstions compated to typical continental breakfasts. Would recommend!

The staff were professional, responsive, and very accommodating. The laser game ate our coins so a staff helped us and ended up giving us a couple extra. They made an effort for fun games, could improve, but did appreciate and had fun! My biggest complaint has to be the age limit on the hot tubs. People bringing their toddlers and babies into the hot tub, they have to be peeing in there. No one under 14 should be in the hot tub, also would appreciate 1 hour before and after just for hotel guest rather than visitors with day passes at the pool. Our entire team got rashes after using the pool. Maybe the chlorine levels need monitoring more on weekends. Smaller issues that were easily fixable: The rooms / windows needed a deep cleaning, (what’s a nice view with dirty windows?), the most uncomfortable hotel bedding I’ve had in my entire life, everyone complained about the heat in the rooms being too much, so the next night I turned down to 60 and it was decent. However no mold in the building which helped keep allergies down. Would consider booking again!

The bathroom fan and heat lamp didn't work so there was mold on the showerhead and grab bar on the shower. Wallpaper was curling up. Floors in the entire room needed deep cleaning. There was water on the window sill. No cover on the heater control panel. The only ceiling light in the room quit working and the lamps were very dim. Beds were clean and comfortable. The waterpark needs a complete overhaul. The play structures were covered in rust and missing paint. The adult hot tub was closed our entire stay, as was the basketball pool area. The snack shack was closed one day of our stay. On our last day, the systems were down so no cards could be used to purchase items at the gift shop/snack area. The lobby area was freezing, and you had to walk through it on the way to and from the waterpark. Many arcade games weren't working. The meeting room we rented served us well, and Max and Brittney were incredible host and hostess for our group. The food from Tony Roma's was delicious, except for the sirloin steak, which was so chewy it couldn't be eaten. The free breakfast was amazing, but the milk and juice machine were broken. Check in was quick and easy. Every employee we encountered was friendly, smiling, and greeted us with a smile. We all had a wonderful time, and it's a safe, gorgeous location on the Mississippi, but it could use a major renovation. We'll definitely be back, and are hoping they have improvements and updates on the horizon.
