Hi! You asked about the Pal Mickey Swap. Pal Mickey is an intereactive stuffed Mickey to take to the parks. He tells you about rides, updates you on times for the parades, reminds you of priority seating, etc. He's $60 to buy. The Swap is where several DISers are chipping in together to buy a Pal Mickey to share during their consecutive trips to Disney. They have arranged to split the cost, averaging around $2.50 per day to have Pal Mickey (PM). Once their turn is over, they will have pre-arranged plans to pass PM off to the next DISer signed on the swap. At the end of the swap, the PM will be delivered to Give Kids the World, an organization which helps give sick children trips to WDW. The two I know of are full, but I'm trying to organize another one. My post for people interested is on the Budget Board.
Hope that answers your question.
