Just got back today from POP and LOVED it.
We normaly stay at mods, and I really didnt want to stay there, but my DH said we had to stay value if I wanted a longer trip.
Well, all I can say is I wish I had stayed there sooner. The difference in room size is negligable, we didnt really notice. The theming is fun with the giant icons, it is a big resort, we were in the 50's building 3 which was very close to everything.
We didnt notice any noisy plumbing, the beds were very comfortable, the pool bar makes wonderful frozen drinks. The airconditioning worked perfectly, our room was always very cold. My DS 14 loved the frozen cokes, and the game room.
It was crowded at the food court, but we always found a table pretty quick and the food was very good, better then at some of the quick service restaurants in the parks.
We are planing another trip at the end of the year, and we will be staying at POP. If you have any questions I would be happy to answer them.
