Our family had a blast at the Castaway Bay waterpark! I appreciate the longer span hours it is open compared to other waterpark resorts we have visited. It was great to get in first thing in the morning and ride the slides without any line ups or waiting!
The room was clean and in great recently renovated condition. The fold out bed in the chair is a clever use if space, and was comfortable for sleep. We didn't prefer the hard floors / lack of carpeting in the rooms. It wasn't as cozy feeling, but is an understandable choice in a waterpark resort.
The biggest concern with hard floors was it was very loud without any sound dampening overnight. Other guests making poor choices letting their young kids run down halls yelling, and slamming doors echoes in the room overnight. We aren't typically light sleepers and haven't had this issue before at another hotel. After 10:30pm our entire family was woken up by a group including toddlers loudly speaking in the hallway, and the repeated slamming of doors for around 20 minutes. Again at 11:30pm it sounded like a young child was running up and down the hall yelling, and doors were slamming. Without carpet for dampening it is very loud and sounds like they are yelling in your room. When people are knocking or slamming doors late at night it sounds like is is your door. Just something to be aware of.
Overall we enjoyed the resort, and are glad we tried it!
