We got a Pal Mickey when we were in Disney last May and it was a lot of fun. He told cute jokes, would tell you when parades or shows were about to start, made funny comments especially on Tower of Terror, you can play games and he kept our 2 year old daughter occupied. If you didn't hear him you can squeeze his stomach and he will repeat what he said. He would come on as we passed certain buildings on Main Street and give little bits of info on them. He would aslo tell us that we should go to Pirates because there was no line. He came with a clip and he didn't get in the way at all. He fit in the bag we brought to the park so it didn't bother us to carry him around. I think I've read posts where people suggest putting a lanard strap around him to carry him as well.
My 3 year old plays with him at home. She likes listening to him tell jokes. It was worth it for us. When we got him he was $50 but I thought I read on these boards that he went up to $60 but I'm not totally 100% sure about that.
