Hello Rachel!
I am excited because you are planning a fantastic Walt Disney World vacation!
Disney's Art of Animation Resort is a fabulous resort! I have had the opportunity to stay in a Little Mermaid Standard Room and a Finding Nemo Family Suite. Both rooms were incredible!
Yes, you can bring your water bottle to Walt Disney World as long as it is not glass. You can fill up your water bottle with water at the soda machines (rapid refill stations) in the
Landscape of Flavors Food Court. There will be a small lever on one of the soda dispensing positions that will provide filtered water when it is pressed, according to my experience. I get water this way to bring to the parks on my Walt Disney World vacations.
Since you are staying at a Resort with a
Disney Skyliner station, make sure that you take a few flights during your vacation to get to Epcot or Disney's Hollywood Studios!
I hope that your upcoming Walt Disney World vacation is magical!
