Hi Tina!
How exciting! Your son will be so surprised and what a wonderful gift to give him!
There are so many incredible Walt Disney resorts to choose from. I think your selection depends on what your son and his bride are most interested in. If it's pure romance, the
Grand Floridian is the best option. It is the epitome of elegance and charm. We spent the beginning of our honeymoon at the Grand Floridian. I really think it sings "honeymoon".
For tropical fun, the
Polynesian Resort is wonderful. The theme is lush and beautiful. The newlyweds will even be greeted with leis upon arrival.
If they want to be closer to some adult fun, I highly suggest the
Yacht and Beach Club resorts. They are walking distance to the Boardwalk which has tons of fun nightlife for adults and it's walking distance to Epcot. These resorts are classic with a nautical theme. The pools are amazing and the views are beautiful at night.
For a little extra surprise, browse through
Disney Floral and Gifts for some amazing romantic creations.
Have a magical day!
