Dirty and Disrespectful place

Liked:Horrible experience. Checked in and went to the room. Pulled out the couch and there was dirty, nasty sheets left on. Yellow stains and blood stains. When I called down they said “we can change them”. I went down and spoke with a manager and they gave attitude and did not even apologize. We checked out immediately. Not a clean or respectful place.

Not worth the price

Liked:We had stayed here several years ago and had a good time, but it has gone downhill. We booked a Captain’s fireplace suite that included a whirlpool tub. Neither the tub nor fireplace worked. The morning after our stay I asked to be compensated and only charged for a room that did not include those amenities. The employee put a note in for accounting and said I would hear from someone after the weekend. I did not, so emailed the resort again, about a week later, but I did not receive a response and it’s already been 3 weeks. The room itself was ok, but the shower door let a lot of water out so very moldy in places. The water park employees were all very nice, but one hot tub was out of order, one pool was out of order, and there is a lot of rust on the water feature. Also a great deal of chlorine in the air, it made my son very uncomfortable after an hour (lungs and eyes). So cannot recommend and will definitely not be returning.

I should’ve read the reviews first

Liked:Don’t stay here! These ppl charged us over $200/night for a junior suite for our family. When we checked in, the nightstand had drink spilled on it and there was sticky spots, BIG sticky spots all over the top of it. As I looked futher, there was some chewy candy stuck on the wooden trim, something white going down the side, and sticky on the drawer with black stuff in the drawer. There was dust on everything- like when was the last time this room was used??? After I saw spots and spilled and food on all the surfaces, I ended up going downstairs and getting cleaner so I could clean the surfaces myself. They offered to move me, but they didn’t have another junior suite available! Fine, percentage off is efficient. Now, I can’t trust anything in the room to be clean, so I ask for new bedding for the sofa sleeper because…. Who knows if it was actually changed. When they brought me new bedding, they said extra pillows were in the dresser- nope! There’s nothing in the dresser and no bibles in the drawers. This place is janky! I’m so discussed to sleep here. I won’t be back! Don’t make our mistake- STAY SOMEWHERE ELSE, then come here and use the waterpark!
