I'd also suggest reading what you can here. Suggestions - look in the Mexico threads and the link that Brian provided to get started.
I looked in the TUG database and I didn't see the location you had asked about. However that doesn't mean that there isn't one there, it means that I didn't know what else to look for.
In order to look at the databaase and reviews, you need to join TUG. Believe me, while you are getting yourself educated on timeshares, and looking to see which timeshares you might be interested in buying, the modest membership fee is well worth it!
Good luck and welcome to this site.
