A few years ago I won a 3-day trip to New York City (I live in California). As it turned out I wasn't able to take the trip before the "must be taken by" date, so when the person from the judging agency called and told me I won, I asked if they offered a cash alternative instead (there was no mention of a cash alternative in the rules). She said, "Yes, actually, we do. You can take $2000 instead if you'd like". I told her I would like, and they sent me a check for $2000. So I would suggest that even if there is no mention of a cash alternative to a particular prize in the rules, it doesn't necessarily mean they don't offer one; so if you're notified that you've won a trip, a guitar, some kind of big-ticket item, etc., and if the rules don't specifically say "No cash alternative", ask about it. Can't hurt.
