Now this time share business can be a little tricky. It's not your usual opportunity. There's a heck of a lot to know if you aren't aware of time shares and how they work.
I won't get into that part because it's not something I'm familiar with. But something has me puzzled about this deal.
Given the supply of time share units is finite - there can only be so many. With a juice, the supplier can always ramp up production to meet demand. Not so with rental units.
So let's see then. Where does GRN get their supply? There are two major exchange companies, Resort Condominiums International (RCI); and Interval International (II) that time share units use. Is GRN geting their inventory from RCI or II - left over stuff nobody wants?
As for the opportunity itself...
Global Resorts Networkoffers two travel club memberships for sale. A lifetime Platinum membership is available for a one-time fee of $2995 and a three-year Gold membership is available for $1495. The Platinum membership is good for life - and beyond: it’s willable and can be passed along to other generations. (Think they will be along forever?)

Now think about this a minute. You have more and more people joing GRN everday all selling a finite number of units.
Common sense dictates that people eventually aren't going to be able to find any units to rent in any location when they want to take holidays.
It seems apparent, to me at least, that GRN is running some type of Ponzi scheme here. Their main business is selling the opportunity at $3000 a pop - not rentals. IMO.
Am I missing something here?
Can anyone with more knowledge of time shares maybe clear up what's really going on?
