Since I have to fly to cruise (I live in the Chicago area), I only travel with one carry-on bag plus a large shoulderbag, I put everything into my carry-on. Clothes (I do laundry halfway through the trip), travel size toiletries (I buy any other items that are too big for the 3 oz air restrictions upon arrivel in my port city), electrinic stuff, ext cord, power strip, travel docs, etc.
If you want a copy of my template spreadsheet containing a planning checklist, packing checklist, itinerary, wardrobe planner, and a tab listing many travel planning & packing checklist websites, send me a PM and include your email address!
I'm currently planning for a trip to my mom's (Miami area) over Thanksgiving and also have columns set up for my march 2010 cruise oin Imagination. Went to my mom's in March over spring break and my list was invaluable!
