Hi Donna,
It's lovely to hear from you again and I totally understand you wanting to book your next visit to Walt Disney World as soon as possible!
The 2013 UK holiday packages were released by the Walt Disney Travel Company in March 2012 so I would expect to see the 2014 UK holiday packages available to book around the same time next year.
The latest information that we have about opening dates for the New Fantasyland was announced by the
Disney Parks Blog on 7 August 2012.
It stated that the grand opening of the New Fantasyland will take place on 6 December 2012. Attractions included in this opening 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.
After this date, the New Fantasyland expansion will continue with the opening of Princess Fairytale Hall in 2013 and the debut of a new Disney “mountain” in the form of the Seven Dwarfs Mine Train in 2014.
When exactly in 2014..........i'm afraid that we simply don't know. I would recommend that you subscribe to the Disney Parks Blog to ensure that you receive all future updates on the New Fantasyland.
Lastly, I like you, would absolutely love to be picked to be in one of the parades at Walt Disney World. Generally, the families are picked at random early in the day. In order to increase your chances of being picked, I would recommend arriving at the parks as early as possible. You could also consider wearing some matching t-shirts so that you stand out and perhaps do some pin trading with some of the Cast Members at the entrance.
Wishing you a magical holiday filled with memories which will last a lifetime!
