I was talking to an acquantiance at a function last week who has 5 timeshares. He said he had turned them in, and received enough credit for two or four(I forgot which) first class airline tickets anywhere, and 4 one week stays and had choice all but a handful of worldwide Marriotts.

This does not make sense to me, as interest and fees for the timeshares (maybe $1500 each) would make this the deal of the century.

I cannot find enough information on Marriott sites, or the timeshare BB to figure out anything about values of turnins, and cost of plane tickets and hotels in points.
