Hi Melissa,
Thanks for visiting Disney Parks Moms Panel.
A trip to Walt Disney World Resort — even with a brief stay — is still an invitation to enjoy all the magic. You can
request a crib when you make your reservation or when you arrive at your Resort hotel. Keep in mind that quantities are limited. While I don't know that a crib would fit within the bathroom space of a
Disney's All-Star Music Resort Family Suite, I have seen Guests arrange the twin sleeper chair, double sleeper sofa, and twin sleeper ottoman next to each other, so that might give you some ideas of what's possible. Another idea to consider is a Family Suite at
Disney's Art of Animation Resort, where the suite is larger at 565 square feet, as compared to the Disney's All-Star Music Resort Family Suite at 520 square feet. That could give you a bit more room to arrange your setup.
Melissa, here's wishing you all a fantastic and fun Walt Disney World getaway vacation.
Enjoy your Disney!
Jerry
