No, I don't think you're missing anything. Wait - you did know about the secret trade-up option for cruises, didn't you? Where one
DVC point counts as 5 for cruise purposes???
Sorry - just yanking your chain a little!!!! Sure, it's an expensive use of points, and many people, like me, would have to bank from one year and borrow from another. With my 330 points, I could have 990 in a year, and that still wouldn't cover all three of us in my family for an Adventures by Disney trip. We could do it for two of us, and we'd have to pay cash for the third. It would cover the smallest inside stateroom, I think, but that wouldn't be as much fun.
I'm more likely to pay cash for these trips, if I ever take them with my children. Now if I were going solo, that might be a pretty good use of a couple of years' points. We'll have to see!!!
Of course, the best option is - buy more points!!!!!!
