In November, they (Koda and Kenai) were in Epcot in Canada and in AK on the character trails. Just check your times guides to see if, where, and when they will be appearing
we found them in the Canada pavillion. Since they were up the stairs from the main walkway through world showcase, they didn't have a crowd around them so we really got to spend time with them. Sitting in Kenai's lap was the most memorable part of New Years Day for my 3 year old!
