Hi Julie!
It is wonderful to hear you are planning your family's next Walt Disney World Resort adventure. Disney's Pop Century Resort is a wonderful resort, but I completely understand the desire to stay somewhere else. My Disney "bucket list" includes staying at every resort, at least once.
If you are able to spend just a little more, I highly suggest staying at one of the moderate-category resorts. Be warned though, once you stay at a moderate it is hard to go back to a value. Even though you never spend much time in your room, the larger beds, area and amenities are very nice. Also, the pools are amazing! My favorite moderate resorts are
Disney's Caribbean Beach Resort and just added to the top of the list this last trip,
Disney's Coronado Springs Resort. We will happily stay at a value if it means the difference in visiting, but if within budget, the moderates are perfect.
I hope I have helped make your choice just a bit easier (honestly, you can't go wrong,) but if there is anything else I am able to assist you with, please let me know. Have a wonderful time planning your trip.
Magical Wishes,
Lauren
