The best part was being able to walk across the street to the show if having cocktails. Otherwise, better options for a hotel in Dubuque.

It was ok - the kids had fun and it was a clean place to sleep. However, the property needs a makeover. Everything was rusty in the water park. Nothing was necessarily a danger to the kids but just seeing all the rust was encouraging. The wall paper was coming off the walls in the bathroom, the carpet seemed to be 100 years old and the furniture similar. But like I said the kids had fun, we slept well and the breakfast was awesome.

Room was not good

The room was decent. Missing 2 of the safety latches in the door and door frame. Door was hard to open and close. Air conditioner was not working properly. Maintenance guy came and checked it out made adjustments and left worked for about 5-10 min after he left. Ron was very uncomfortable and it was hard to sleep there.

Location was perfect. Was in town for a concert and couldn’t have picked a better location. Staff was very attentive and friendly. Only draw back was they didn’t have a shuttle. But that’s minimal. Didn’t attend the waterpark due to timing. Have heard many positive remarks about the facility and waterpark.
