I am a list maker. I have travel lists in my computer: things to check, things to ship, things to carry on, things to keep handy if we drive…
While I was clicking around trying to help my sister prepare for her upcoming vacation I found this great site: IndependentTraveler.com.
I was most impressed with their Packing & Accessories page. They have a great interactive packing list and carry-on compliance listings. Their packing tips are handy, too, if you're not a regular traveler.
They even have a nice bit about family vacation planning.
It's a handy website to have in your favorites.
