Hi, Lenore! Of all the value resorts,
Disney's Pop Century resort is my favorite. I love the theming, I think they have the best bus transportation of all of the value resorts, and I love the tie-dyed cheesecake available in the food court.
Disney Vacation Club members who are using their DVC points for a reservation do have the option to take advantage of Complimentary Alternative Pool Use, also known as
Pool Hopping. Pool hopping is available at many of the other resort pools, even some of the non-DVC resorts, however, Art of Animation is not a current participant in the pool hopping option.
There is quite a list of
DVC Membership Magic Benefits that you might want to browse. While none are specific to Disney's Pop Century Resort, you might be able to take advantage of some of the dining, shopping, or recreation discounts during your visit.
Good luck to the gymnastics team, and have a wonderful stay at Walt Disney World!
