DH and I had great interaction at Chef Mickey's and the Epcot Visa pic stop, not so good interaction with the face characters at 1900 PF. But - that's not stopping us from Tusker House and CP next trip!
To me, there's almost nothing better than getting a hug from an old friend. I wasn't sure I'd care when we went 2 years ago and finally made time for characters, but it just takes you right back to being a child again.
