Rooms were dirty, pull out couch was clearly not changed or cleaned. Smoke detector was actually pulled out of ceiling and missing. Crazy when we all actually had to leave building or room up main floor due to fire alarms going off. They could have mentioned when we booked, no liquor license and could not serve in restaurant or hotel. Just run down and needs more help and upgrades but kids had fun, so we made best of it.

The gentlemen that checked us in was courteous. He told us there would be brunch in the morning from 6:30-9 a.m. When we got there, there was no brunch. There was a to-go breakfast in paper bags. The signs in the resort show pictures of the breakfast - sausage, eggs, etc. - very misleading. When I asked the lady at the desk this morning about the breakfast, she just shrugged her shoulders and said she didn't know.

Employees didn’t seem to know any information except to check you in. Couldn’t help with my problems with checking in. No bathroom close to entrance when checking in. Make sure to bring earplugs if you want to go to the water park or pool!!!!! Room was ok except for a VERY short shower curtain. Breakfast was very poorly staffed and not enough employees to keep up with putting it out. Gets 2 stars out of 5 🙁

Disliked: Cleanliness
The room looked great but ... there were 3 (pubic) hairs on the toilet seat and 2 long, dark hairs in the shower. No toilet brush, and the A/C was very loud, extra-dirty and when turned on - filled the room with a smell of burned garbage. The breakfast was ok - better than in many other places. However, the first morning, the eggs had an awful sour taste. On Sunday morning, the area was crowded and SOOO dirty - tables were sticky, food was on the floor, and no seats available for 2 people. People were having breakfast in their sweaty and smelly pajamas, some were watching loud videos on their phones - this, however, is not the hotel's fault. But maybe, just maybe, you can set some ground rules in place, other than just 'shirt and shoes' which, c'mon, is just common sense.
