One thing I didn't think about (and just wanted future cruisers on points to keep in mind) is that if you have to cancel your cruise for any reason, they are "reservation points" and cannot be used for the regular DVC resorts any longer. I knew that when I made the reservation but I was confident we would take the cruise so no biggie - until we had to cancel. Now we are stuck paying (with a member discount thank goodness) cash for Hilton Head in November, we're out the exchange fee (which we knew about), and have 182 reservation points that no matter how I do the math and which concierge collection hotel I pick, we will be losing some points since these points will expire on July 31st. Fortunately, a stay at the Yacht Club will use up all but 2 of those points so we're grateful for that and my son is happy about our upcoming "extra" trip.
So I would just caution anyone considering a cruise that even if there is a good chance your plans might change, you may want to consider paying cash for this additional reason. If we were paying cash and had to cancel, we would just get our deposit back and be using points for the Hilton Head trip. Oh well, just thought I would share my experience. Of course your mileage may vary but there are just too many variables with my hubby's vacation schedule and other things for us to ever use our points outside the regular DVC properties anytime in the near future.
I'm sure this info is nothing new to most DVC members but for any newbies out there considering using points for the cruise, this is just another little tidbit to keep in mind. Happy planning everybody!
