Hello, Amanda,
Thank you for your question to the Disney Parks Moms Panel. I imagine starting to plan a 4th trip to Walt Disney World is so much fun for you! Both
Disney's Art of Animation Resort and
Disney's Pop Century Resort are fabulous resorts while being budget-friendly. To help you decide, why don't you let your son look over the pictures of both resorts and their rooms and get his input? You can also find additional pictures of both resorts at the independent website allears.net. Similarly, there are also videos on YouTube of
The Little Mermaid rooms specifically as well as general videos about both resorts if that helps, too.
If the trip is going to be a surprise, perhaps you could ask your son his thoughts under the premise that a friend has asked you for your feedback since you have been there several times. He'd be helping to secretly plan his own trip! I think by involving him either directly or indirectly, you'd have a better idea of which resort he'd find more fun and exciting.
If you have further questions as you continue to plan your trip, please let us know. We are happy to help! -
Kara
