If I banked Dec 08 I'd have to use them before Dec 09. So I wouldn't be able to have a 3 year point buildup for a Dec 09 Christmas vacation (banked would expire Nov 30, 2009). Right? OR do I have until Nov 30, 2009 to make a reservation with those 2008 points?
keep in mind that
UY month has nothing to do with when you can book a room. if you have any concerns about UY impacting when you can call to reserve a room, please disregard them completely before continuing.
now with that out of the way, from what you have described, you banked your
2007 pts in june of 2008...therefore, they will expire at the end of november 2009 and you can't use them for a reservation in dec 2009.
that is correct. you would need to rent or find another way to use those pts.
to book dec 2009 with a dec UY, you would bank your
2008 pts (the ones you get on dec 1, 2008) and then call in jan 2009 to book dec 2009 at your home resort...at that time you can borrow your 2010 UY pts if needed.
banked dec 2008 UY pts: good for stays 12-1-09 through 11-30-10
dec 2009 UY pts:good for stays 12-1-09 through 11-30-10
borrowed 2010 UY pts: good for stays 12-1-09 through 11-30-10
(again, to book during that period with any of these UY's pts, you can call at 11 months out at your home resort or 7 months anywhere.)
if you have to cancel more than a month out, a december UY is great because you have a full year to use any pts you have banked or borrowed into the 2009 UY...and plenty of time to decide whether to bank any current UY pts.
if you cancel less than a month out, you still have a full year to try to use your "holding pts."
if you are often traveling in december, a december UY is terrific.
