Wow Beth, you are a wealth of information! Thank you for typing that all out for us.
I didn't even realize there was a character greeting area in Epcot. I knew there was one for Disney Visa people, but the one you mentioned is for everyone, right?
Luckily, DS is not a princess fan, so that knocks out most of them for me! He is a Mickey fanatic though, and never got tired of saying hi to him, and hugging him.
We did happen upon the Pooh characters at AK, and that was awesome! A CM actually pulled us aside to go meet them, as there was absolutely nobody there! The characters were all decked out in their holiday wear too, which was cute. We got some awesome pics- even one of all three of us. The Photopass guy took so many pics, and we were able to take a lot of time there. For anyone who is interested, it's just outside of the Dinoland (or whatever it's called) section, down a trail, kind of hidden.
