The pool and pool area was nice. We liked how there was a separate adult pool from the kids pool. Also, the room was clean and had clean towels everyday. But, they allow dogs which was not a pleasant experience. Yipey dogs during the day & night was very disturbing and annoying.

The room was spacious and had a feather bed that was almost too soft. A/C was good, and we really liked having a ceiling fan too. Shower was huge!
