Jennifer,
There are plenty of romantic places, it just depends on what best matches your temperament. So I will give a few suggestions, and let you choose from there;
California Grill. Schedule your dining to end roughly around firework time at the nearby Magic Kingdom. They dim the lights, pipe in the soundtrack, and you get the bird's eye view. My all time favorite for romance.
Victoria and Alberts. The most formal affair at Disney World, and priced accordingly. Cuisine is exemplary, the personalized pampering is wonderful, and the formal setting is a break from a theme park vacation.
Jiko. Beforehand explore the hotel lobby and the savannah viewing area, then get a cocktail in Victoria Falls. Afterwards, return to the savannah view and sit by the bonfire and snuggle.
Rose and Crown. Not a match to the other four for cuisine, but the outdoor seating area is wonderful, especially if can get a table for the Illuminations show.
As for in the room, the Polynesian's room service comes from the
Kona Cafe menu.
I hope this helps. If you want further suggestions, just ask me directly by going to my bio page!
Have a delicious vacation!
