Hello, I am new to the idea of exchanging my TS weeks. I recently bought 4 wks, 2 B/2Bat the Grand Mayan in Cabo. I don't know what I was thinking as I never need more than 1 BR except for the fact that the salesman said that I could rent out my studio. I am having a difficult time figuring out how to do so. I told the salesman that I would not be able to use any of my wks this yr as I have already used all my vacation time. He said, "no problem, they will be banked automatically for you so that you can use them next year". Well, I tried to bank them with the resort and was told that it would be better to bank them with SFX. When I tried to contact SFX I was put on hold for 45 min. I hung up after that. When I called GM in Cabo to try to book some of my 8 weeks available in 2009 I was told that there were no availabilities until June and if I want a week in June I have to be one of the 1st people to call as all the rooms are taken within 3 hours. When I go online I find that it is very easy to rent a week. So basically I spent a small fortune for a TS that I can't get into- I do not want to go to Cancun or PV. They tell me that other TS are available. Does SFX work or is it a scam?
