I don't think the taxes will be as bad as some people have imagined they will be. My letter from Ventura asks for my SSN so they can send me a 1099-MISC, so it gets entered as income. I do my taxes with Turbo Tax, so I just pretended I had a 1099-MISC for $6000, and my refund only went down $900. I didn't even get to the fair market value part of the prize (meaning, they can say the prize is worth $6000, but if I use the hotel/park hopper/flight price that my friends pay for the same accommodations when they go with us, I can call that the Fair Market Value of the prize).
Still, $900 for a family of four to fly to DL, stay at a DL resort, and get 5 days worth of park entry, plus the $1000 gift card and $500 shopping spree, is pretty *pardon my French* damn good!
