Hi Tara, and welcome to planDisney!
I know the feeling, and I have been there on more than one occasion where I want a specific resort, and I will check and check until I find an availability. Of course, we are talking about Walt Disney World Resort, so I am always prepared with a backup.
I took the liberty of searching the
Walt Disney World Resort website, and currently, there is no availability for all of your dates at
Disney’s All-Star Music Resort. However, have you searched by the day? I cut your stay down to 2 nights, and availability does currently exist (for now). If (when you search) two of the three nights are available, you could reserve those nights and then resort hop to another resort for the last night. I resort-hop at least once per vacation because I like the variety, but it could be a vital option if you can get some of your proposed dates. Please note that availability can be fluid; an opening could pop up anytime before your arrival date. I recommend having a backup resort reserved, and when an opening occurs, you can modify your stay at that time.
Please return and let us know if you have additional questions before your arrival.
Have a magical vacation!
Raquel
