Hello Robert,
Amid all the candies and hearts, I'd choose you and Disney as my birthday Valentine! What a great way to spend your big day!
At this time, no special events have been announced. But keep an eye out here for any updates. In the past, I also know several Disney restaurants have had special menus tailored for Valentine's Day, so you may want to check with some of your favorites as you get closer to your trip.
I think a great way to commemorate your 2011 birthday visit would be to pick up a Duffy the Disney Bear decked out as Cupid for the holiday. I saw a picture of him taken by Fellow Moms Panelist Suzannah at Zannaland.com.
Or if you're looking for something more on the romantic side, have you ever tried a
Fireworks Cruise or an intimate horse drawn carriage ride at Fort Wilderness?
No matter what you choose to do, I hope you have a wonderful birthday!
Enjoy your trip!
