We booked a stay-cation here for the recent 4th of July weekend and we are certainly glad we did. We rented a casita right next door to the water park; we also had a pool right outside out suite which was really nice. Friday and Saturday nights they played movies by the poolside in the water park. Families laid out on lawn chairs and wadded in the pool while enjoying Despicable Me and Despicable Me 2.
The rooms were just ok. For a casita, I'd expect a small stove of sorts being that you're given a kitchen area with full size fridge, sink and microwave. Our small couch was broken, but my nephew found a creative way to sleep on it anyway. My daughter said the sofa bed wasn't all too bad. My accommodations upstairs lent a huge king size bed all to my lonesome and it was surely nice and comfy.
Parking was awesome; there are 3 spaces under the casitas and you can park on the street in front of your door.
The staff was fairly pleasant; except for the kids that work the water park (they acted like they didn't want to work).
Calling reservations is useless; you're better off booking online and calling the front desk with any resort specific questions. Book with AAA if at all possible. Download the Hilton app which allows you to check in online and choose your own room. Fantastic! No long checkin lines.
Admission to the water park is included in your stay, regardless the type of room. Regular hotel room gets 4. 1-bd casita gets 6 and a 2-bd casita gets 8. Anything over that and they are supposedly $30 per wristband.
I'd recommend. We're definitely going back!
