Janet,
I have been checking around, and I have never heard of the Princess Parlour that you mention. Can you send another question with more information on where you heard or read about it? We can do some in-depth research and find out more, but the name alone does not ring any bells.
There is a Disney fan website by that name, but no actual location in Walt Disney World, to my knowledge. Here is a little known Princess-themed activity that might be what you are looking for;
My Disney Girl's Perfectly Princess Tea Party - This is an expensive experience, but it is the height of Princess-themed indulgence. Don't confuse this with a traditional English tea. There is such an experience at the same venue (
The Garden View Tea Room within the Grand Floridian Resort), but this party is hosted by Princess Aurora. A small gathering of Princesses swarm the room in every princess gown imaginable as they are showered with presents, tea, and finger foods.
As I said, write me back with a bit more of what you have heard, and I will dig a bit more!
Have a magical vacation!
