Depending on your budget, I've heard that one of the most romantic meals you can have at WDW is at Victoria and Albert's at the GF. Have not had the opportunity to try it yet - DH and I have our fingers crossed that we'll get a ressie for our upcoming October trip.
Some of our romantic favs:
Afternoon tea at the Grand Floridian - we take turns pre-ordering something special from the GF bakery to surprise each other (last time I ordered Cinderella's slipper...it was divine). We also order a glass of champagne with our tea.
We like to order cookies and milk from room service at the Beach Club on the first night of our stay (we're DVC members and we usually stay at the Beach Club Villas) and then take them out on the balcony for an evening snack under the stars.
The Food and Wine Festival - if you ask me the whole set-up in the world showcase is romantic. We eat our way around the world, sharing everything...feeding each other, getting each other tipsy, generally acting like fools. It makes for a very liesurely afternoon and during the weekdays it seems less crowded than it is at night, especially when the Magic Kingdom is hosting Mickey's Halloween party.
Strolling the Boardwalk at night...playing some of those silly carnival games and then renting one of the tandem bicylcles.
We haven't tried any of the spas at WDW, but I'm a spa junkie and it's on the list for this year! I make sure on every vacation we take that there is some type of massage or facial or wrap...well you get the picture! Even better if you can have a couples spa experience, but we've also done different treatments at the same time. One of the best couples massages we've ever had was actually on Castway Cay when we sailed last October on
Disney Cruise Line - it was a cabana massage on their adult beach. Unbelievable and unforgettable.
This thread is a great idea - I've enjoyed reading all the ideas!
