This is an amazing location for character meet and greets!
My most recent visit to Epcot I was able to get Joy and Sadness (the wait in line was a bit long but certainly worth the wait!)
You can fastpass for the character spot if you would like. I also saw Baymax there but he does not sign and I had my picture done with him prior so I skipped that one. The line for him was a shorter.
Back in the World Showcase you can meet the princess for many of the countries, plus see Alice and/or Mary Poppins (yes I have her autograph-I had to stand up straight to get it too).
You never know who you might see, keep your eyes open and make sure to grab a Times Guide when you enter the park. Enjoy!!
