Hi Karinne! Obviously there is something very special about dining in the castle for any guest of any age. However, if you are looking for the best princess character dining experience then I would choose the Akershus location in the Norway Pavilion of EPCOT. Your daughter will meet and greet more princess characters at this location over the castle. These might include Belle, Jasmine, Snow White, Sleeping Beauty, and Mulan. Both are great but the decision will come down to location or number of princesses to meet!
There are two tea party activities at the Grand Floridian you might be interested in doing. One is the My Disney Girl's Perfectly Princess Tea Party and please click
HERE to read more about this event. The other tea party is the Wonderland Tea Party and you can click
HERE to read a short description. One is more expensive then the other but you also get lunch and a doll so you need to decide what is best for your daughter and her age. I only have grandsons but I know if I had a granddaughter I would be signing up for these as quickly as possible. What fun to sit and be a princess and little lady for an afternoon!
For the complete princess makeover don't forget about the services offered at
Bibbidi Bobbidi Boutique in the Magic Kingdom or Downtown Disney. It is a perfect way to start a day and then head over for some princess dining in the resorts or parks!
