No Luggage?? LOL
Okay, here's more of my list because we travel back home about 11-12 hours and I like being prepared...
EZPass or iPass for tolls
GPS
Phone chargers for cars (should always be in there but check)
Wall Phone chargers in luggage
Luggage
Pillows (because of allergies to down pillows in hotels)
Sometimes a blanket, but especially to cover luggage if we have a lot
Paper plates or foam plates
Plastic cutlery
Paper Towels or Napkins
Munchies (usually hard candies, licorice, sometimes snacks to keep at my parents so we don't eat all theirs)
Cooler
Bottles of water for cooler and pop sometimes (beer when my husband sneaks it in there)
Different jackets/coats because we go through varying climates
If it's winter a small snow shovel and rock salt
Emergency road kit in trunk
