Hi Ana,
We are all soooo excited about the Fantasyland Expansion! I can hardly wait to see it, too. To help you explore how it will look, I'll let the Disney imagineers helps. If you click
here and
here, you can hear about Under the Sea, Journey of the Little Mermaid.
If you click
here and
here, you can explore a couple of other blogs that will provide you further information about the expansion.
As for the making reservations, no information has been released about that yet. However, I'd encourage you to continue checking the
Disney Parks Blog as well as doing periodical checks to see if Be Our Guest is listed in the online reservation system by clicking
here.
Please let us know if we can help again. My fingers are crossed that you will be able to enjoy dining at the new restaurant next year.
