Wow, I had no idea so many people unpack!
I never unpack. Dh does, but not me (and I am in charge of dd's suitcase, so she doesn't either, lol). I find that if I pack my suitcases in an orderly fashion, there is no need to unpack--the suitcases function just like drawers. Shirts in one side, shorts in another, underwear and socks in a pocket. Shoes and toiletries come out of course, but they have their own suitcase anyway. (the whole family puts shoes, toiletries, and other bulky items like coats if needed into one large suitcase. Then we each have another suitcase for the rest of our clothes. One large collapsable duffel goes down with a pillow in it that we throw away there (if need be) and bring it home full of stuffed animals that dd has to have, lol. Dirty laundry goes into a bag and all dirty laundry comes home in one empty suitcase so it's not in with any leftover clean stuff. We bring a lot of suitcases, but we are very organized about it.
I would kill for a washer and dryer in my room, but I am too in love with the Polynesian to go to a DVC resort. Maybe some day when dd is older.

I do laundry if we stay over 7 days, which we usually do. It sucks though, and wastes my time! The Poly needs washers and dryers on each floor, or at least, in each building. That would be nice.
