I think the cameo is just Pete's voice of Disney Prices being high in the beginning of the video.
It's a great video though I think I may have commented on you tube about it already but I agree that Disney vacations(and vacations in general) are priceless!
This is the same family but there first video. We are leaving on Thursday for wdw and we have been getting the kids ready, my 12 month old watches this at least 3 times a day lol http://www.youtube.com/watch?v=OQHfvKIqr1s&feature=related
Awesome video and awesome ending. It made me think about the moment my family has started creating our memories. He summed up in his video what I try to explain in people why these trips are so important to me and my family. You can't make up that love they all share.
