Hi Julie,
I think I might have just answered a similar question from your husband! I know it can be worrying to find the perfect resort for everyone's needs. I told your husband about Disney's Beach Club Resort, but I think Disney's Art of Animation might also be a good choice.
Disney's Art of Animation has fantastic family suites. The family suite would give you a separate bedroom for privacy and a kitchenette for convenience. You will also find the incredible
Big Blue Pool. I think your water loving teens would enjoy this amazing pool.
I know mobility is a concern, so I want to give you a little information about room locations. Rooms in the Finding Nemo section are closest to the Big Blue Pool, while some of the suites in the Cars and Lion King sections might be a bit closer to Animation Hall, where you can find the lobby, Landscape of Flavors food court, arcade, and shopping. The Lion King section is the closest to the bus stop.
Wherever you choose to stay, I hope it's a magical vacation for your family.
Please let me know if I can answer any other questions.
Amy H.
