The characters appeared at the deck shows--mickey, minnie, goofy, pluto, chip, dale. They plus others appeared through the week in the atrium for signings and pictures and other times unexpectedly. Lots of the characters from disney dreams also appeared for pics. There is a schedule in the atrium on the moniter for the next day with specific characters. Just carry your camera with you at all times.
We were walking through the halls after mickey and minnie were down with a signing and as she passed our son, minnie gave him a big kiss!
