Congrats! That is wonderful and Disney is a great place to celebrate! We've celebrated a few of our dating anniversaries at Disney and will be celebrating our first anniversary there this year. There are no special packages that I know of, but there are so many options to make your trip special, it just requires some advance planning. Be sure for your hotel and dining reservations to note that you are celebrating your anniversary and be sure they put down that it's your 25th. There's no guarantee that they will do anything but you will usually get a nicer seat at the restaurants and possibly printed menus and things like that. Also wear the pins, you will get lots of congrats from CM's and other guests which is nice.
Some special things you can do:
- Cirque du Soleil
- Spa treatments
- Dinner at Victoria & Albert's
- Illuminations or Wishes Cruise
- Custom Anniversary Cake
- Special tours
- Stay at your dream resort, or stay CL
- Carriage ride at Port Orleans or Fort Wilderness
- Order something from Disney Florist
- private parties arranged through Disney Catering
There's basically something for everyone. I would definitely recommend a meal at V&A's, the food was amazing and the atmosphere is so nice. We had our first post-wedding dinner there and it was just perfect.
