I would like to arrange to have Talking Mickeys waiting for my grandkids when they arrive at their room. I won't be arriving until a few days later so I can't do it from there. Is there any service that would arrange the surprise at the BWI? Do the Talking Mickeys only talk when they are moved around the parks or can they be prompted to talk at any time? Are they appropriate for a 2-1/2 year old and a 4 year old?
