It really sucks to hear about the problems that people have had with Worldmark. I've been a member with them for over 4 years and actually worked for them for about 6 months as a salesman (I'm now working for the government for much more money ha ha).
I wound up leaving the Worldmark job because i was being "too honest". Not that they were lieing, but they just didn't want us to give too much information, otherwise your guy/girl would spook and not want it. I would give people the worst case scenario when it came to things like trying to make reservations, etc. I just don't like withholding information that would be detrimental to their enjoyment of the product. I really do enjoy the resorts!
That, and I am of the mindset that if someone tells me they can't afford it, then I leave it at that and thank them for their time. Every person is different, they know more about their finances than I do...and I'm sorry, but I'm not going to try and convince someone who just old me they can't afford it otherwise just because I want to make a sale. If they can't afford it, I'm not going to shove it down their throats.
Granted, there are "professionals" who go to these things for the gifts, but those are few and far between. Far better to be honest and do good business so you can keep customers, right?
When I joined, I was lucky in that the guy that sold me mine was straight up and honest about it. I knew exactly what I was getting into. Believe it or not, they are legit...I've stayed in two of their resorts (San Diego and Orlando) and plan on staying in their Vegas one in early November. Unfortunately, there are those in the company whose demeanor give it a bad name. I can tell you as a person who not only owns but used to work for the company, it is a legit establishment.
Just be careful when you go to the presentations. Stick to your guns if you can't afford it, but also don't automatically dismiss it because of other people's behavior. I'm sure the other complaints on here are legit, but please just keep in mind that that isn't the entire company.
If you can work it out financially to get this product, then I do highly recommend it. Just do what is right for you.
