We bought a Pal Mickey two trips ago and he'll keep returning with us, but sometimes he's a bit of a pain.
IMHO, you need to have a child that is VERY willing to carry Mickey. Yes, he's cute, but I carry a backpack and don't want anything else. But, I have to admit that Mickey was religated to the backpack on many occasions.
We also have a DS (he was 8 when we got Mickey) that has to retell EVERY joke that Mickey tells!!!!! Yes, it's ok for a few DAYS, but by day 5, well, you get my point.
Also, sometimes Mickey would "shake" (meaning that he had something to say) and we would be someplace that we just couldn't hear him. Oh yeah, this was especially distracting for my DS - he just couldn't ignore Mickey when he shook. Do you know what it's like to have a DS8 who can't get Mickey off his clip, press his belly, and hold him to his ear to listen to him talk WHILE WALKING!!!!! I really surprised the boy never hurt himself.
Anyway, with all that negative talk, we keep taking him back. Overall, I really do like him and if you don't get one you'll always wonder if you're missing something. He also can be used while waiting in line - listening to his jokes (AGAIN) or playing the "games".
Besides, isn't it very "disney" to walk around the park with a Pal Mickey on your belt????
