We had characters at our Swan wedding! They are booked through Disney, not through the S&D. We had Mickey & Minnie in their formal wear. They showed up at our reception & the DJ introduced them. They were alot of fun. They stayed for 30 minutes, danced with us, the guests (everyone from ages 1-77 loved them!), & posed for pictures with us.
Our reception was indoors. I thought I read that Disney has specific rules about having the characters join outside events (maybe to prevent the possibility of guests running into two Mickeys within a few minutes of each other).
