Would I do it, personally? Definitely not. But I agree, do whatever the fuck you want with your life. It is yours to live as you please.
A close friend of mine got flown out for a free weekend in Vegas for one of these things and invited my best friend and I to meet her out there (driving) and stay with her in her free hotel room and party it up (also just to be there in case he ended up getting creepy/violent/etc.). She didn't do anything with the guy, and he did end up being creepy (obvs) and tried forcing himself on her but luckily she has a black belt and was able to put his arm in a you-move-and-I-break-it hold LOL. He paid for her to have spa treatments, dinners, shows, a really nice hotel room separate from his own (which the three of us all enjoyed hehe), and he gave her $3,000 cash as an allowance to have while she was there I guess. She took us out shopping and bought me my dream shoes.
All in all, that trip was fucking crazy LOL. We decided to go with her on a whim at 2am the night before and the experience is something I will never forget. She ended up leaving early and driving home with us because the guy just started getting too weird and no, she didn't ever end up having sex with him.
That was one of the best Vegas trips we've eva had.
