August, 2006 we stayed at the Grand Mayan in Nuevo Vallarta, and after Seven hours of high pressure promises we purchased. Based on an "Equity Exchange" of our Florida timeshare, we were required to sign a contract that waived our five day cool-down or right to rescind period. According to Mexican law, this right cannot be waived. The Grand Mayan used fraudulent sales practices to keep us from canceling our contract-EVEN THOUGH WE STAYED THERE 7 MORE DAYS!!! We lost sleep and felt sick but had been told there was no way out. We were told we would make $2500 a week when renting out our unit, when in fact, according to various websites, i.e. ebay, tug2.net,TimeShare User Group, etc.. we would be lucky to rent a week for $800. We were told our salesman had contacts to get our full value from our Florida property (after we were allowed to purchase it back from GM for $1)-Lies! You pay $300 to get it listed and never hear from them again! Travelers BEWARE OF THE GRAND MAYAN! We have requested our contract to be canceled but to no avail as of yet.
