Hi Ayumi and welcome to planDisney.
You must be super excited now that there's only a few days to go, before you arrive at
Walt Disney World! I cannot think of a better place to get into the Christmas spirit. All of the Disney Parks and Resorts will be decorated beautifully - it's such a wonderful time of year to visit.
Unfortunately, no luggage of any type is permitted on
Walt Disney World Resort buses or, the
Disney Skyliner.
I think that in your situation, the best thing to do would be to leave your luggage at
Bell Services when you check out, at
All-Star Music Resort. Then, once you have enjoyed your meal at Topolino"s Terrace, return to collect it, before heading to the Airport.
If you are short on time, I would suggest utilising the
Minnie Van Service or, a ride-share service, rather than the complimentary
Resort Transportation, on your return trip to All-Star Music Resort.
Alternatively, you can try to modify the time of your meal, to a little earlier, on the My Disney Experience Mobile App.
Either way, I would recommend arriving at
Topolino"s Terrace approximately 20-30 minutes prior to the time of your reservation, to ensure that you are seated on time, or, maybe even a little earlier.
I hope that this has answered your question, Ayumi and that you have a brilliant time at the Most Magical Place On Earth, next week.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
