I have stayed at POP 7 times. Sometimes I do preferred, some not. I like 4th floor for less noise and nice view. However usually elevators are behind you to get to buses/food. I don't mind stairs! So think about your preferences. Bottom floor no stairs but more traffic. 2/3 floors get a "view" but not too many stairs. Go to the POP page because there is a map showing which areas are preferred.
The preferred are in 70's, 60's and 50's. Do you like any theming over others?
Really can't go wrong, I have stayed all over the resort and loved it all!
