Always Carry A Bunch of Plastic, Closeable Bags In Your Suitcase
(Los Angeles, California)
I highly recommend packing 5-10 closeable plastic bags in your suitcase. You will be happy to have them. When you pack to go home, these are handy for wet cloths, dirty and smelly cloths, liquids that might spill, souvenirs that are liquid and might spill and many other things.
I also agree with the website author to only bring a carry on. Sadly, most of the airlines now charge to check your luggage. Save money and time by bringing your suitcase on the airline.
