Aaron - I too have been to Grand Cayman and I saw my fair share of chubby girls there too. I think just about anywhere you go is going to have them. What part of Jamaica have you been to? Ocho Rios and the Dunn's River Falls area is very different than Negril. True the locals are pretty damn poor and basically survive on what they make from tourists, but that is true in lots of resort areas. The hotels in Negril are pretty nice. Maybe not the Venetian, but better than many motels I have stayed at in the US. With the climate there I doubt a nice Vegas style resort could stay nice for long. Way too much upkeep vs. the environment there.
The beaches in Negril are some of the best on the island.
Yes, there is PLENTY of smoking going on in Negril, but what else would you expect there. No smoking in Negril would be like no gambling in Vegas. Just because you are there does not mean you have to do it. There were plenty of people last time who did not smoke. The whole idea there is to have a good time with friends. If you want a trip surrounded by lots of babes that you don't know then try somewhere else. Those of us who do go will get to enjoy each others company in a unique setting
It is definately better than any show in Vegas!
