We did Afternoon Tea at the Grand Floridian last May, I think exactly a year ago today, actually!

My DH, DS13, DS10, and I enjoyed this very much!
They have pre-set "meals" you can order which would include tea of your choice, finger sandwiches, scones, tarts, strawberries and cream, pastries, etc. OR you can order anything individually, a la carte!
My DH and I LOVED the scones with Devonshire cream and raspberry jam.......Mmmmmmmm!!!
They have a children's version too which includes chocolate milk and peanut butter and jelly sandwiches and other selections.
Our server was wonderful and made suggestions to us and made a couple of substitutions.
We did this as a late lunch, after spending the day at Typhoon Lagoon and it was a wonderful way to relax after a tiring day!
I have a couple of pictures of our Afternoon Tea on my "family vacations" web site, the link is below!
P.S. I also suggest making a PS because you wouldn't want to be disappointed and miss out on this!
