They are definitely a scam! We recently went through the presentation and even though we have always purchased timeshares on the resale market, this deal sounded really good.....too good to be true, in fact. We bought, went home and read through the details, did some internet research and then immediately canceled our contract.
They sell you 5000 points for $9,000 with only $252 per year fees. They tell you that they have a special relationship with RCI and that you'll be able to book weeks 18 months in advance, even before the owners themselves can book you can book as many of these weeks as you want for very low weekly cost. They even show you some examples on the enlarged computer screen, which seem fantastic. Never mind that you can't book at the Sapphire Resorts until within 30 days of use, the big benefit they tell you is booking RCI Extra Vacations. Well, when I looked at the RCI directory, I realizes that "RCI Extra Vacations" are available to all RCI members. So it seems that what you are buying is a lifetime RCI membership. Clever scam, with clever usage of terminology. A big rip off. Sadly, they are selling successfully to the majority of people in that sales room.
