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 We have stayed many times at this hotel and it is outdated but this experience was a first where the room was in shambles and disgusting.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 The rooms are outdated and need a deep clean.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.

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.

Family weekend get away

Hotel overall was good. Hotel was clean. Breakfast was surprisingly really good!!! Arcade and water park was average. Definitely well used and could use some up grades. The one downfall was the smell and amount of chlorine used in the water park. It hit you once you walked into the park. We could only be in there maybe 2 hrs and the kids started to cough so bad almost vomiting and our eyes burned for a couple hrs after getting out.
