Has anyone had experience with renting or selling a timeshare through Global Resort Management? I am leary of the company because they want an upfront fee, and because I can't find any information on them, other than their website. They claim they have corporate renters/buyers for the timeshares in the Orlando area. The offer sounds good, but is it too good to be true? I am also unsure how they received our contact information, since we did not have anything listed. Thanks.
