We were in Mazatlan in April and also went to the presentation. The people are very freindly and informative. They have lots of information on this project and are very excited about it.
They guarantee to rent your suite for the first five years and to sell your "other" timeshare if you have one at a very good price. They show you two prices (on paper) one if you buy a one bedroom and one if you buy a two bedroom. Your eyes light up and you think WOW!! what a deal.
My advise..start running now and sign NOTHING!!
This original piece of paper diappears and the "guarantee" becomes a "guarantee to PUT INTO INVENTORY" by another company (Sierra), anything they promised you verbally is replaced by a clause in the contract that states that the written contract replaces any oral promises.
If you have signed...quickly read
