It's not just the types of incentives you've already mentioned but also other "deals." DH & I cruised the last week of Oct. '09 and learned that we could book this year's TransAtlantic cruise for a substantially discounted amount of points. We had to book within 3 days of leaving the ship. It was too good a deal to let go so we're going on the WB TA in Sept. Keep asking the
DVC folks. Kara was especially helpful!
During our cruise they were offering great deals for add-ons. Wish we were in the market for more points. Not for us at this time, sad to say.
