Hi Tomas! Walt Disney World is a wonderful place to celebrate an anniversary!
Although the week of Christmas is extremely busy at Disney, park attendance levels for the rest of the month are generally quite low. I would expect very little crowding during the week you're visiting. The beginning of your week will be the least crowded, but you will notice the attendance levels in the parks creeping up each day as you get closer to Christmas at the end of your visit.
While Disney certainly has lots of upscale restaurants where you could have a romantic anniversary dinner, you don't have to spend a lot to celebrate at Disney World. First, be sure to note on your resort and dining reservations that you're celebrating your anniversary. When a restaurant or hotel knows you're celebrating, you may be surprised with a free dessert after your meal or a congratulatory card in your room. Guest Services can provide you with buttons to wear so that everyone will know
that you're celebrating an anniversary on your trip. You'll be
stunned at how many people wish you happy anniversary as you stroll
through the parks!
Fantasmic is a spectacular evening show at Hollywood Studios, and just outside the theater you can purchase a Dessert Tray with a glass of sparkling wine to enjoy during the show for about $20. Another romantic way to spend the evening would be to take the monorails and boats from the Magic Kingdom to visit the Grand Floridian, Polynesian, Contemporary and Wilderness Lodge to see the beautiful holiday decorations. At the Grand Floridian, you can purchase gingerbread at a life-size Gingerbread House in the lobby! Some other fun, and best of all, free ways to celebrate at Disney World include
watching the Magic Kingdom fireworks and the Electrical Water Pageant from the
beach of the Polynesian or strolling around the Boardwalk watching the street
performers.
