We stayed at POP 2 times this year and really enjoyed it both times. We have stayed at all the moderates and a couple of deluxe resorts at WDW.
While there is nothing like Polynesian, for our money, POP is terrific. We enjoyed the theming a lot. It's very colorful and fun. We also thought that POP had the absolute best transportation of any of the resorts we've stayed at. While the busses get crowded at peak times, we usually only waited 10 minutes or less. When there is a long line, they'll load 2 busses at once.
DD12 loved being able to get slushies in the refillable mugs (although the machine was broken about 1/2 the time). We also felt that the food court was very good for breakfasts or a snack.
All of the CM's we interacted with were delightful people. They wanted us to have a good time.
I don't think you made a mistake at all.
