A 1 bdrm week 32 is worth 17 TPU's.
Grandview is one of many properties managed by Daily Management Resorts (DMR). Their system is kind of a hybrid mini-system. You cannot exchange to other properties internally thu DMR. You have to belong to RCI and make your exchanges just as you would to any other RCI properties. When you go to book the exchange, the fee will be a reduced fee of $139, instead of the usual $199.
If you choose to join RCI, you can deposit your week and get 17 TPU's. You can then use that to exchange back into Grandview for about 8 TPU's for a 1 bdrm or 12 TPU's for a 2 bdrm (or less in many cases). So, if you really like Vegas, you can get 2 weeks at Grandview for the 1 week you own. Factor in all the RCI fees and getting that 2nd week will cost you less than $350.
You'll also have access to getaway weeks where you just pay a fee for the exchange. You're really not exchanging anything, just renting a week. For Vegas, Orlando and other overbuilt places, those rentals can be often be had for under $350 as well.
While RCI might cost you something more, it would allow you to stretch your ownership into more vacation time and lower your avarage cost per week significantly.
