i travel lots for work, and for pleasure. I normally have my cosmetics and toiletries, and blow dryer, as well as other misc. items such as the over the door shoe hanger packed all the time.
Then I have all our snorkel gear cleaned up when I get home, and stored in a suitcase so I don't have to hunt around for that stuff.
In another suitcase, I keep some stuff that I would only ever wear on a cruise, like all the swimsuit covers and stuff like that. I normally don't have much to pack when we get ready to go.
I also make a little check list that I have photo copied, as well as a project plan, so I can do a final check a week or so before to make sure that I have not forgotten anything.
