The pool hours at the Polynesian were always adjusted throughout the year. In the Summer the hours are longer to go along with the longer days and warmer temps. The biggest change is that the pool use to open at 7 AM and the closing hour was adjusted throughout the year. In the summer it use to close at Midnight.
The new posted hours are the hours that the gates will open when scanned so there will be no entry to the pool areas before or after hours. Each person in your group will have to have a magic band that accesses the pool gate and I am told they will use their portable scanners to check people or look for people without bands. This is nothing new. The pools at the
Disneyland Hotel and the Grand Californian are gated and require a key to enter.
Storm-A-Long Bay has required each person to have a wrist band or magic band. In February my friend was walking into the pool area with her kids and the kids were not let in until they had their bands to scan.
Both Polynesian pools will be gated and hours of access will be limited.
