Hi Ellie!
Disney's Art of Animation Resort is my little ones favorite Disney Resort hotel. They ask almost daily when they can go back to the 'Mater Hotel'. The Resort is so well themed, and the pool areas are full of splastashtic fun for your children to enjoy. I hope you and your family fall in love with this Resort just as we have.
Your group will fit perfectly in a Family Suite at
Disney's Art of Animation Resort. The Family Suites sleep up to 6 Guests plus one child under the age of 3 years-old. In the Master Bedroom you will find a queen sized bed, and in the living area there is a full size convertible table-bed and a full size pull out couch. For your 18 month-old you will be able to request a pack 'n' play crib, or bed rails to place on a larger bed for safety. Another great thing about the Family Suites is that they come equipped with 2 full size bathrooms. I find this so helpful when my large family is trying to get ready to explore the theme parks each morning. The Family Suites are adorably themed after some of your favorite Disney and Disney Pixar films including; Cars, Finding Nemo and the Lion King. I encourage you to check out the above linked web page and choose the section that appeals to you the most.
Ellie, if you have other questions about your upcoming stay at Disney's Art of Animation Resort or any other aspect of your trip, please just let me know. I love to help fellow Disney-loving families have the most magical time possible on a Walt Disney World vacation.
Have an Animated Day,
~Jen
