That's right. You can deposit your points and then have up to two years to choose where you want to go.
They do it a little different now than a couple of years ago, but I used banked 1999 (could be used originally from 10/99 through 9/00) points for a week at VB in September of 2001. I deposited the week with II and just made the trip to Hilton Head this past spring.
Unless they changed the rules (which I don't think they did) when they went from a deposit of a week, to the point deposit that they do now, you can do this.
