Hi Diane! Lucky you! The Grand Floridian is absolutely amazing! Your daughters are going to love this beautiful resort, and I would venture to say that you will, too!
Making Advanced Dining Reservations for Character Dining is not difficult to do, but the choices can be a bit overwhelming. The wonderful Cast Members are always available to help you make decisions when you call them at (497) WDW-DINE.
Or, you can make your reservation online, by clicking
HERE. This webpage will tell you all about the different Character Dining choices available, as well as some specific information about the location, the menu, and the characters which attend. You can also make your reservation online from this website by clicking on the particular Character Dining Experience you want to do, and following the instructions.
Now, as for suggestions... there are some Character Dining experiences held right at the Grand Floridian, and they are absolutely magical!
1900 Park Fare has the "Supercalifragilistic Breakfast", the "Wonderland Tea Party", and "Cinderella's Happily Ever After Dinner".
Some of my family's other favorites are "Chef Mickey's" at the Contemporary Resort, breakfast at "Akershus Royal Banquet Hall" in the Norway Pavilion in EPCOT, and "Cape May Cafe" at the Beach Club Resort.
You can't go wrong with ANY of the Character Dining experiences! Best Wishes to you all!
