I am weeks, which is week 30. Because I haven't been an RCI member, I have no points (said I could have had 16k+), but she said if I was I would get the points assigned to the week from RCI, but she could not tell me how many for the week. Not sure what that all means but maybe it answers you question
Some units at this resort are already enrolled in points when you purchase from the developer. However, if it's not already enrolled, it's not a good value to enroll it now, because they charge thousands to enroll it.
You can use it to exchange in the RCI "weeks" program (TPU/trading power units) - just not the points program.
Just checked the RCI calculator. A one bedroom at Grandview ranges from 12 to 21 TPU, depending on which week is being deposited. If OP's ownership is a floating week, and they played the system, they could get the most for it. 2019 is not yet available to deposit. So it's a toss-up right now.
