The economy is a considerable source of concern but we're still vacationing a fair bit this year. I suspect next year will be more frugal unless things improve. This year because we bought the GCV addon (our first, and almost certainly last addon), we got the "free" cruise. This allowed us to take our usual annual trip to WDW, a small trip to the much closer DLR, and a cruise all in the same year. Lucky us, but it feels like a bit much with the world falling apart.
In the future it's the non-Disney trips that we'll probably skip, because at Disney we have the timeshares, everywhere else is pay-as-we-go. This is no doubt the whole point of
DVC for Disney. We're going to miss the Hawaii trips that we normally take in the summer (Disney in winter). Here's hoping that things improve. (I sure miss the Clinton / Gore years at times like this).
