Super fast and friendly check-in. Waterpark was a bit run down, but my 4 and 1 year olds had a blast. Breakfast was decent. Room was clean, with some wear and tear. It was a good, quick getaway for the kids!

Waterpark a blast!!

Waterpark of course was the highlight, we had a blast despite the strong chlorine. Rooms were ok, bedding very wrinkled.. not a good first impression wasn’t sure if room had been cleaned or not. Seemed like furniture was missing.. large empty spaces.. like maybe chair and table removed? Weekend we were there very crowded with spring breaker, staffing for breakfast could have been better.. they were out of everything and the two working were running like crazy… other guests were not helpful or polite no fault of the gals trying to keep up with demand.

For $500 expected more

Top sheets and comforters clearly aren't washed as there is cheeto fingerprints all over the beds. The bath tub faucet drips constantly, many large blemishes on walls, honestly disappointing for what you pay.

Not so great

Our hotel room had curtains missing and broken. The chair in the room was broken. There were red stains on the floor all over the room. We have stayed many times at this hotel and it is outdated but this experience was a first where the room was in shambles and disgusting. Half the arcade games are broken. The water park could use some love.

Rooms need updated

If it wasn’t for the Water Park and my grandkids, I would never stay here. The rooms are outdated and need a deep clean. The carpet in the room was disgustingly dirty. Im glad I brought socks to wear. The breakfast in the morning was very good! Nice variety of foods offered. The water park was good. The kids loved it. Could use a few more tables and chairs to put your belongings on. Everyone of the staff we encountered were so friendly and helpful! Overall it was the rooms that were the negative for our trip.

Needs cleaning and maintenance

The waterpark needs a good cleaning and maintenance. Several of the interactive water elements were broken. Many of the games in the arcade were out of service. Our floor smelled of weed upon our arrival as well.
