Just got home to see follow-up responses. I'm not an attorney, will never pretend to be one, but can at the very least make mention of "issues" that I'm aware of that may allow you to make appropriate inquiries. Again, I would never say that the state of the law "is" (quote unquote) something. I don't think any good attorney would ever do so. Lawyers that I know oftentimes joke that the outcome of a case or any issue within a case, assuming a non-jury trial, may hinge on what the judge had for lunch that day. Ya never know how the judge will respond to any argument/set of arguments.
Issue: in what jurisdiction must you sue? I'm assuming it would have to be where the resort entity and the resort entity's sales office would be. Remember that the alleged purpose of the legal system is justice and fairness, and it would be both unjust and unfair to force any defendant to defend in a state distant from where the defendant does business. Maybe you could argue that Wyndham might do business in your state, but might Wyndham (assuming you choose to sue it) prevail by telling the court that our witnesses don't live in your state, the activity complained of did not occur in your state, it's not the proper site for this type of lawsuit. That argument could possibly be made by Wyndham prior to a trial actually beginning, as they would likely file a Motion to Dismiss (making arguments why it should be dismissed due to the improper forum).
Parties: The timeshare salesperson is an agent of Wyndham. Hence, it appears to me that principal (Wyndham) and agent (the salesman) law would apply. And most times a plaintiff would prefer to sue both because the principal most often has the deep pockets. A suggestion has been made that you just sue the salesperson. In that case, it's pretty certain (in my opinion) that the suit would have to be brought where the salesperson resides.
Principal-agent law: Someone has suggested that Wyndham might say, "The salesperson made a mistake but our other salespeople are great". As far as I know, a principal is responsible for the actions (or inaction) of his agent. Hence, the likelihood is that Wyndham would never say such a thing as that to me appears to be an admission that may very well lead to a judgment for the plaintiff.
Proof: I believe that the standard of proof in a civil case is "more likely than not". In a criminal case, I believe the standard of proof is "beyond a reasonable doubt". Therefore, the standard of proof which must be satisfied to prevail is not as difficult as it is in a criminal trial. It's still not insignificant, however. I leave it up to you as to how you might establish "more likely than not". But, again, in a non-jury trial, it would be the judge who would make that decision, and his decisions would be made based upon not only on all his prior knowledge of the industry, etc., etc. and whatever evidence you provide (including your personal testimony that he may or may not find "credible", but also whether or not he likes you and what he had for lunch that day.
Attorney's fees. Some jurisdictions award attorney's fees to whomever prevails in the litigation. Some jurisdictions never award attorney's fees to either party. And some will leave it up to the discretion of the judge.
Small claims court. Aside from whatever the damage award limits might be (although you're really looking for the termination of your contract in addition to the return of whatever amount of money has already been paid), there may be limitations on who you can subpoena to come to the court and testify. For example, if you sue only Wyndham, you might not be able to subpoena the necessary salesperson witness, as the short but sweet small claims court case may not allow any more than the parties to appear. I would also check on whether ANY small claims court case ever involves the award of attorney's fees to either party.
Can you appeal a Small Claims Court case? I believe you can. The Small Claims Court, as far as I know, reduces the number of cases that would involve the Civil Court, but doesn't preclude you from filing in the Civil Court if the result may not have been satisfactory to you.
Judge or jury? That's tough one. Normally, when an industry has such a bad reputation, you might choose a jury trial in that juries are oftentimes more sympathetic to the little guy than the big corporate behemoth (assuming you sue the principal, Wyndham, as well as the agent). But, in this case, the more knowledgeable and informed judge may be more aware of how crooked the timeshare industry is. Maybe the jury might not have that knowledge, and may think the timeshare entity is just your normal business that gets lied about by gold diggers. Tough call. But if it's going to be Small Claims Court, jury trial will likely not be an option.
But before going the "court" route, I would exhaust every other possible means. State Attorney General, Better Business Bureau, any Consumer Fraud office, etc.
Maybe first send a letter to the District Manager of that Wyndham district, tell him what you were told, say you're still waiting to be contacted by the financial firm's rep, and ask why it's taking so long. And then see how (or if) he responds.
And if it does go the court route (whatever court), it might be a good idea to look into Legal Services Plans to have all your questions answered at no additional charge (after first paying for the legal services plan, annually or whatever).
