First: Congrats. If these are current-year (2008) points, that's cool (mine are gone).
Second: Please let us know if HGVC waives or has waived its ROFR. Its nice to know.
Third: Your options with respect to current-year (2008) points are limited:
1. Deposit to RCI for next 2 years -- deposit 2008 points for future exchanges.
2. Rescue for use next year -- you can save 2008 points for use in 2009.
.... Your next-year (2009) point-stretching options:
1. Deposit to the following year -- you can deposit 2009 points for use in 2010.
2. Coverting to HHonors points -- convert 2009 points to HHonors (rate = 1:25).
For 2008 points, I suggest that you "rescue" your 2008 points for use in 2009, and consider whether to use your 2009 points in 2009 or "deposit" them for use in 2010 (which you must do by 12/31). While a deposit to RCI gives you more flexibility, RCI reservations are less certain.
