re: Drinking mixed drinks at a Mexican Resort around Cancun?

One thing I've done that you might consider: if you're on one of those all inclusive deals, tip the bartender before he starts mixing. You wouldn't believe the difference in alcohol amount they will pour in that glass. And it doesn't take much money, maybe a five. They remember you and from there on your stay will be much better. It won't take fifteen pina colatas like the guy that posted above.
