Hi Christina,
Thank you so much for visiting the Disney Parks Moms Panel with your question! I love that you are going to take advantage of the pool hopping perk for Disney Vacation Club members while you are at Walt Disney World. What a great way to see the other resorts!
I checked with Disney Vacation Club cast members, and have learned that yes, you can pool hop to Disney's All-Star Music, Movies, and Sports Resorts, as well as Disney's Pop Century Resort. The only Value Resort where pool hopping is never available to Disney Vacation Club members is Disney's Art of Animation Resort.
I do suggest that you check out the full pool hopping policy in either Disney Files magazine or online at the
Disney Vacation Club member website. From the homepage, go to the tab for "Membership Magic" and choose "Perks." Pool hopping information is listed under "Rest & Relaxation." Please do note that there are certain blackout dates when pool hopping is not available, and you cannot pool hop to any pool if that pool is at capacity. It was suggested by a cast member that you can ask your resort's Guest Services to contact the recreation team at the other resort to be sure that the pool is not at capacity before you travel to the other resort.
I hope that this information is helpful for you, Christina. Please do not hesitate to ask if you have any further questions!
