Hello, Sheena!
Welcome to the Disney Parks Moms Panel! I have seven members in my family, so I TOTALLY understand your question!
I would 100% recommend booking a suite at
Disney's All-Star Music Resort. The biggest advantage with a suite is that your family will have a living room area for additional sitting space and the ability to move around each other. With a group that size, it will be really hard to maneuver in two standard rooms at
Disney's All-Star Sports Resort. Another HUGE reason to stay in a suite is the convenience of having a kitchenette. Having a microwave will really help in preparing baby food! (All standard rooms in the All-Star Resorts do not come with a microwave.)
To answer your question about booking two rooms, you can definitely request two adjoining rooms; however, adjoining rooms are not guaranteed.
Because of these reasons, that is why I would definitely stay in a suite at Disney's All-Star Music Resort. My family has stayed here several times, and we LOVED it!
If you have other questions, please let us know!
Have a MAGICAL day!
Wes
