There are 3 rotations, and they're usually booked based on the makeup of your party....and they're coded on your KTTW card like this: LAPLAPL (Lumiere's the first night, Animator's Palate the second, Parrot Cay the third, back to Lumiere's, etc), or APLAPLA, or PLAPLAP.
The rotation you're talking (APLAPLA) about is usually for those with young children, from what I remember.
We had LAPLAPL with our 10 and 11 yr old, and were in Parrot Cay for Formal and Semi formal night.
