Clarification...
The OP found this site right after she bought and was able to rescind under the terms of her contract.
Just to clarify a point for "Chrystelle" (post #9 above), the ability for a purchaser to rescind a developer-direct purchase has nothing to do with "terms of her contract".
Regardless and irrespective of any such contract terms or content,
state law provides the legal right to cancel a developer-direct contract within the "cooling off" period specified by the applicable law in the state of purchase.
Typically, the rescission time period provided by applicable state law is 5-7 days, although it is as few as 3 days in some states (Massachusetts, Ohio, Indiana, Vermont, Connecticut). In Florida (and in a very few other states, including Tennessee) it's 10 days. In Alaska, it's 15 days.
Once the rescission period provided by the particular state law ends, so too
ends any further option for a buyer to cancel the contract and purchase. Weeks, months or years later is much too late to be able to just unilaterally cancel a (voluntarily executed previously) contract and its' associated timeshare purchase.
