Hi there, Zaida!
Thanks for posting your question to the Disney Parks Moms Panel. Your vacation next summer with your adult son and his girlfriend sounds wonderful. As a lifelong Disney fan, I can attest that you're never too old to embrace all the magic that Walt Disney World Resort has to offer.
The two bedroom villas at the Disney Vacation Club resorts are spectacular accommodations. If it is important for you to have access to a full kitchen and in-room laundry facilities, I would definitely give them close consideration. Among the many options, my favorites are the two bedroom villas at
Boulder Ridge Villas at Disney's Wilderness Lodge and at
Disney's Beach Club Villas. The access to Epcot that Disney's Beach Club Villas provide make them an excellent choice for a party with young adults. The tranquility, beauty, and Northwestern theming of Boulder Ridge Villas, however, make them my overall favorite.
If you don't need a full kitchen or laundry facilities, you could save significant money by reserving two separate standard rooms at a moderate or value resort. Ask for adjoining or connecting rooms at Disney's Port Orleans Resort - Riverside and it is similar to having a two bedroom villa. Last month, several of my friends and I had connecting rooms in the newly renovated section of Disney's Pop Century Resort and it definitely felt like we had all the benefits of a two bedroom villa at our disposal. It was fabulous!
My advice would be to price out both options and then decide which amenities are absolutely critical for your trip. There's no sense paying for more amenities than you will use. Do let us know if we can provide any additional advice as you plan. We'd be happy to help!
Wishing you many magical memories,
Jill
