Here is the info (it was cheaper two years ago-what wasn't- and no parents stayed with their kids):
Wonderland Tea Party
Even children can experience some of the charms that the Grand Floridian has to offer in one of its most recent offerings, the Wonderland Tea Party. At this pint-size tea party, guests from 3 to10 years of age will hear stories, have a little lunch and be entertained by some Disney characters known to participate in a famous tea party of their own. The children will take a hands-on approach to their dining as they finger-paint/decorate their own cupcakes and munch on heart-shaped peanut butter and jam sandwiches. Chocolate dipped Rice Krispie squares, and the Grand Floridians special brand of childrens tea (aka apple juice) is also served.
The Wonderland Tea Party is offered Monday and Wednesday and Friday afternoons from 1:30 p.m. to 2:30 p.m. and the cost is $28.17 per child. There is a maximum of 25 children to ensure that each child gets a lot of personal attention from the entertainment (Mad Hatter & Alice usually, but this is subject to change) and the recreation Cast Members. Parents are welcome to stay and observe the fun, but may prefer to use the time to book a spa treatment, shop (in the elegant Grand Floridian shops), take a walking tour of the beautiful grounds, have a quick lunch at the Grand Floridian Café, rent watercraft at the marina or just sit and enjoy the ambience of the magnificent lobby. Call (407)WDW-DINE to book this or check with Guest Services at the resort. This can be booked 120 days in advance.
Cancellations must be done at least 24 hours in advance or there is a $10 no show charge. Children attending the Tea Party must be potty trained and must arrive 15 minutes prior to tea-time.
