We LOVE Pal Mickey. Esp. if you have a child. Pal mickey was sooo useful in keeping her entertained as she went through WS, for example. He had plenty to say throughout the countries, as well as the other parks.
I love it, and recommend it. I am a die hard disney fan, so it was also something I just knew I had to have. And, yes, DD still likes to play with him at home (he asks trivia and plays games).
Added: He only works at WDW.
