Oh crap. That's quite a pickle. Do you have the right, yeah, absolutely. It's your wedding, your vacation. That said...
If she already knows how you feel about him, and still wants him to go to Mexico with her, then you will be risking the friendship if you tell her she can't bring him. I don't know her, but her reaction might be to tell you she isn't going if he can't go too.
Another option may be to tell her that while she is a cherished friend, and her being MOH means the world to you, you're concerned about his ability to behave himself given his past behavior, and thus he's not welcome at the wedding events. I still think that would go over pretty poorly, but if you really want to address it with her, that's how I would position it.
The other alternative is to leave it alone to preserve the friendship. Have a close guy friend or two - preferrably big, husky fellows - act as security and keep an eye on him. If he can't behave himself, get the onsite WC to call hotel security and have him escorted away from your event. You could even discuss it with your onsite WC when you meet with her before the festivities begin.
My future FIL is the expected troublemaker for our wedding; I didn't want to invite him, but my FI insisted even though they are not close, and my FI always tells me how much he can't stand the man. So fine, he'll be there, but if he starts acting like an ass, we will have him thrown out! (this is the man who asked my FI last month if we wanted to wait another 3 years to get married...uhm, no. No we do not want to wait until 2015 to get married).

They just went on a vacation together and he got ejected from three bars (in a 3 day time frame) for starting fights and eventually ended up in jail the last time for assault and disorderly conduct. He just got out of jail today. Why she is still with this loser is beyond me but he is not welcome at my wedding. I told her that when they first started dating because he does drugs as well (I know real winner!). My FI has told me he will flip out if this guy shows up at our wedding too. So my questions are:
1. Do I have the right to tell her he can't come since she's the one paying for her stay at EDR?
2. How do I even go about this without ruining our friendship or pissing her off so that she doesn't come?
