"PRIZE: Upon verification of eligibility, the grand prize winner and a guest will be flown to Los Angeles where they will take a private VIP tour of the Sony Pictures Studios where portions of the movie was filmed. In addition, the winner and guest will be invited to attend a private screening of Spider-Man 2 and receive a Spider-Man prize pack. .... Winners are responsible for payment of all taxes on the prize and for any other expenses associated with the prize not specifically described herein."
There's no mention of a hotel room or any meals, so apparently the winner is on the hook for his/her own hotel and meals. Pays to read the fine print, doesn't it?
