Hi Patrice!
My husband and I honeymooned in Walt Disney World almost 22 years ago, and enjoyed 13 years of Disney vacations before our first son was born - and we loved every minute of these treasured vacations together!
One of the amazing things about Walt Disney World is that from the Parks to the Resorts to the Attractions & Experiences, there is something for everyone, and everything and everywhere is very inviting and welcoming to ALL! Even the "fanciest" of the Disney Resorts is welcoming to every generation.
That being said, I would recommend Disney's
Coronado Springs Resort if you are looking for a spot that would probably host a greater percentage of adults than the others.
The reason for this is that it was designed to be a convention center type resort. It is a very large and spread out moderately priced resort for this reason, but you will find great amenities such as superb Table Service restaurants and other dining opportunities, shopping, and even a full-service salon. Opportunities for activities include a gorgeous swimming pool and sand volleyball court, along with a nature trail perfect for a romantic hike. Coronado Springs is even home to the largest hot tub on Disney property, with a capacity of 22 people!
Check it out and see if it just might be the getaway you're looking for!
