Has any one used those space saving storage bags; the ones that you put your clothes in, zipper shut, then roll them and all the air comes out. How well did they work? Was your stuff all wrinkled when you took it out? Finally, are they worth buying? 

in them so we really don't care if they are wrinkled or not.

If I didn't split things up like that they would end up with mismatched outfits for the last few days of the cruise. It does make it ALOT easier to unpack on the ship too. DD's bags go on one shelf while DS's go on another.
