This is exactly my argument for DVC, or any way you can make sure you travel on vacation (not necessarily to see family) once a year. Fortunately, DH also likes to travel, so he does agree on that point. He didn't really do much traveling as a kid, and since we've been married we try to take at least one trip a year (sometimes more).
For those that have asked - I gently broached the DVC subject as we were getting ready for bed last night. I said that I legitimately wanted to talk about it in the next day or two, and didn't want him to dismiss it until he'd heard me out. I said you know me - I would never in a million years be proposing that we do this right now (particularly since we won't be back to Disney until likely late 2007) if I didn't think it made some sense and was a good deal. He agreed we could talk about it Friday night.
But then laying in bed, out of the blue he starts asking questions about what type of accomodations? how many points would it cost to do this at this time of year? where else can we go? and we could rent points out if we weren't going to use them?
I consider that a positive sign - we'll see!
