I love the Tea at the Grand Floridian.
I have dressed up but gotten there and felt overdressed so now I go with just a nicer pair of Capris or pants (depending on temps/time of year) and just a nice tee shirt nothing that would look out of place for the parks but just a tad nicer then then plain park clothes. You don't have to dress up but it does add that little touch of "special" for me.
In terms of what to order: My mom and I love the Buckingham Palace package. It includes a tea, scones with Devonshire Cream, tea Sandwiches, and you get a choice of either 2 desserts off the dessert tray or Strawberries w/Cream.
My mom loves the Garden View Blend Tea with her BP package. I am more of a Chocolate Milk type person but have heard good things about most of the teas at the Grand Floridian.
Hmmmm its been almost 3 months since I went last....I think its time to go back soon!

I

the GF Tea. My favorite place on property to take a break!
