This was a fantastic experience. The staff was so accommodating and helpful when my kids had some sensory issues. The rooms were clean and everyone was friendly. The water area is great. There was plenty to do and the slides were super fun for kids of various ages. It’s a large space, but small enough that it was easy to sit, rest, and keep eyes on my kids. We definitely plan to come back. The entire area was beautiful.

The resort is ideally located. Short walk to casino, museum and restaurants. The river walk was great Had a good dinner at Tony Roma's and enjoyed the music on the terrace. Swimming pool was closed and there were small kids allowed in the hot tub. Breakfast was so-so....no muffins or rolls? Need two pancake machines....

The big bummer was that the waterpark was closed the whole length of our stay. So we didn’t get to use that at all. The breakfast wasn’t that great in our opinion. The room was good and the view is always amazing. Great location!

Loved the location, amenities, breakfast and impeccable staff. It does seem that the property could use some overall upgrades and though there were many amenities, some were unavailable. The kids club was closed and the waterpark didn't open until 3pm. I understand due to us being there Tuesday-Thursday, but it was kind of disappointing. We found other fun things to do in Dubuque.

We had a great weekend stay! The staff was friendly, welcoming, and always willing to help. The waterpark was a lot of fun and kept everyone entertained, making it a perfect place for families to spend the weekend together. While the waterpark could definitely use a fresh coat of paint and some cosmetic updates, it was clean and served its purpose well. Overall, it’s a great spot to meet up with family and make fun memories together
