If you're not eating at the Crystal Palace, the best places I can think of are--
1. Across from the Many Adventures of Winnie the Pooh ride, near the Pooh playground in the Magic Kingdom. It's usually pretty crowded here.
2.Boat dock in the Animal Kingdom-- the entrance is on the pathway between Discovery Island and Dinoland USA. This is usually less crowded.
3. Pooh often also meets in a room in the back of the shops in the UK Pavilion in Epcot.
Have fun!!!!
