I've been an owner for less then 2 hrs and already have a list of 82 items
A couple of things that I'm adding that I didn't see mentioned (or missed):
Reynolds makes a hand held vacuum sealer that works on their special plastic bags. I'm packing one of these to take air out of coffee grounds, sponges, etc. so that everything stays fresh while we are away.
I'm going to add a family log/journal to keep some notes about all of our visits now that we are official
DVC owners! We'll just jot down the dates of our visit, our ages, what we enjoyed, how much a gallon of milk costs (LOL!). I think it will be fun to look back on this when our lease expires in 2042

I am going to pack some of those plastic pockets that are adhesive so we can stick in a photo of our family on the trip, maybe our room keys or other keepsakes.
I'm packing our pressed penny collection. We never look at it at home, but when we are there we always find new machines.
Nail polisher remover (sometimes those manicures don't last through the vacation)
The rest on my list is pretty standard: shampoos, medicines, first aid stuff, etc.
