When bell services picked up our luggage they labeled it for whatever resort we were heading to. We have never lost anything! And they didn't complain about my 90 pound suitcase two years ago.
To make all this moving around possible, I pack everything in those "space bags", sorted in whatever way makes sense to me when I'm packing. I also pack some empty bags, so that as clothes get dirty I have a place to put them. I put the bags of clean stuff in the drawers, and I have very few things that need hanging (I usually bring one "nice" outfit for me and one for DH which I pack at the top of my suitcase and hang immediately when we check in). Even shoes get a space bag. This way, my "walked-around-all-day-smelly" sneakers aren't perfuming the rest of my luggage or my room!
