Hi Gustavo!
Welcome to planDisney.
While all the "All-Star Resorts" - Disney's All-Star Music Resort, Disney's All-Start Movies Resort and Disney's All-Star Sports Resort - are located close to each other, and within short walking distance, it is not possible to walk from any of these resorts to
Disney's Art of Animation Resort (or to any of the other Disney Resort hotels).
If you wish to use Disney Transport, it's a fairly easy transfer between hotels - you would take a Disney bus from your All-Star Resort to Disney's Hollywood Studio. Buses begin running approximately 45 minutes before park opening times, up until an hour after closing. From there you need to board the
Disney Skyliner which will take you to Disney's Art of Animation Resort. The Skyliner is a smooth, comfortable ride, high above the resort. You'll feel like it's an attraction all of its own!
Once you arrive at Disney's Art of Animation Resort, you will be within close walking distance of
Disney's Pop Century Resort. You are very welcome to explore both hotels and enjoy some dining and check out the resort gift shops. You can also view the pools but unfortunately, use of the pool is limited to guests who are staying at the resort. Fun fact: The Big Blue Pool at Disney's Art of Animation Resort is the largest of all the Resort hotel pools at Walt Disney World!
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical vacation to Walt Disney World Resort!
