Hello Katherine! Welcome back to the Disney Parks Moms Panel.
During our first trip as a family of 4 in March 2015, we stayed at
Disney's Art of Animation Resort and started off in a Little Mermaid Suite with an infant sleeping in a pack and play. It was not enough room, especially when my son developed a hacking cough that was keeping his older sister awake at night.
We switched into one of The Lion King Family Suites which would allow us to separate brother and sister into different rooms for a better sleeping arrangement. Before we settled on setting up the pack and play in the bedroom with my wife and my daughter and I taking the 2 beds in the main area, we tried the pack and plays in various locations; including the bathrooms.
The pack and play will fit in both bathrooms with a little more wiggle room when placed in the on-suite bathroom connected to the main bedroom.
Your kids will have a blast at Disney's Art of Animation Resort whether swimming in the
Big Blue Pool or soaking in the
larger-than-life ambience of the Family Suites.
Good luck with your sleeping arrangements!
