Hello, Allison!
Oh, you are in for an extraordinary trip to Walt Disney World in May of 2013! There will be so much to do and see, PLUS the New Fantasyland Expansion will have so much more in store for you!
Take a look at this
Disney Parks Blog post about the New Fantasyland Grand Opening, which is set for December 6th. Be sure to subscribe to the blog, too, so that updates are sent directly to your inbox. Among the exciting new attractions and restaurants are Under the Sea - Journey of The Little Mermaid, Be Our Guest Restaurant, Enchanted Tales with Belle, Ariel's Grotto, Gaston's Tavern and Bonjour! Village Gifts. Princess Fairytale Hall will open some time in 2013 as well, but no date has been released for that as of yet.
Have fun perusing the blogs about this exciting expansion! There are photos of the buildings, interviews with executive chefs, menus listed and so much more! I know that you and your little princess and little prince are sure to be so excited just by reading through those posts, you'll wish that May were just around the corner!
