So I just looked to see what I can find on this from people who have been to these things. I got a phone call that I won a bunch of things with a 3 days/2 nights stay at a Wyndam all-inclusive in the Bahamas/DR/Mexico. FH and I are going on Wednesday night but I wanted to know if I'm going to leave with a voucher in my hand. They told me no obligation to buy anything. It's just a presentation and lasts about an hour or an hour and half. I'm kinda excited but I haven't really told anyone until I have that voucher in my hand and we know what we are going to do with it. I'm TOTALLY ok with going to the Bahamas for 3 days and just paying airfare.

Please only reply if you've been to one of these things. What I've read online is that people THINK it's a scam but I read about 3 posts on different blogs saying that it was legit. I'm just trying to see if anyone else has gone to this and what information I can get from you.

TIA!
