My kids (ages 4 & 6) are obsessed with meeting Mickey on his birthday. . They've been drawing him pictures and making happy birthday cards like crazy, even though we're still 6+ months out. During meet and greets, are you allowed to give the characters things, like pictures and birthday cards? Or should we send them in the mail,ahead of time? I already told them they can only give Mickey one picture or card each, but I don't know if characters will even take them during meet and greet times.
