I'm so glad you found TUG and were able to rescind your purchase. You can now take your time and figure out what is best for your situation, both near term and more long term. You should get the green post card back to confirm their receipt of your certified letter rescinding your purchase.
Within a couple of weeks of their receipt you should see a credit back to your credit card for the deposit and initial fees. If you paid by check, they should send you a check to reimburse you 100% of what you paid when you bought. Did you return the "new owner" materials? They may call you or threaten to charge you a fee if they are not returned. If you have to return them in order to get 100% of your money back, be sure to send that certified, return receipt requested as well. Other than that, they could call to inquire as to why you rescinded but I doubt they'll bother.
I'll leave the suggestions regarding whether or not to buy FF/Wyndham or at which resort(s) to others who are more experienced with FF/Wyndham points. I have a couple of FF fixed weeks that have been satisfactory in trading through RCI, but neither is especially great. A points based system will give you the greatest flexibility in terms of resorts, length of stay, unit size and time of year. Being on the east coast, many would say FF/Wyndham is an excellent option for you.
If you are especially interested in FF/Wyndham, you may want to join the FF/Wyndham YahooGroup . . . which is free. You can do so my writing them at:
Fairfield_timeshare-subscribe@yahoogroups.com . Not only are there some really bright FF/Wyndham owners there, but you will have access to a wealth of information contained in the resources files which for many of us, are invaluable.
p.s. It may be best to have this thread moved over to the FF/Wyndham forum so that it gets the most exposure to the "Wyndham" experts
