4/10 Fair

First our room had mold on the carpets and the air conditioner unit had mold on the vents which we didn’t notice till the next morning, the water park had one slide closed and one hot tub closed the play area had a foam pad to keep people from hitting their head on the metal kept falling off when kids were going thru, overall it was not a very good stay, breakfast was good tho
Verified review

6/10 Good

I have stayed in many places where I felt the physical plant was much nicer and paid less. I guess I was paying for the water park, which I was not using. Breakfast was so, so. Was expecting the rooms to be more. Was sure glad when I got home and had my higher toilets that I did not have to pull myself up off of. Staff was helpful when I needed a room nearer the elevators. The elevators were quick and quiet.

Humidity is always a problem in a Waterpark hotel, the bathroom ceiling particularly in our room had seen its better days. Nothing that changed functionality, but it was cosmetically noticeable. Good location, we have stayed here in the past and will stay here again, the kids love it! Breakfast is good too.

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

The room had an odor to it, the counter with visible streaking, didn’t have a top sheet on one of the beds. Visitors be made aware of an extra $50 they tack on that “will fall off” if nothing is broken. Don’t assume the pool has normal operating hours, we checked in late as we had a long drive there. Pool closed at 9p. With hopes of hitting it up in the morning before checkout, it wasn’t open. They do accommodate you can use it after check out, but still didn’t even enter the open pool hours. The pool was only open 3p-9p. The staff there were lovely though, they were all super nice. Typical place with a cool pool where they update the pool but not the rooms.
