Add me to the list, I check a 27 inch suitcase plus I have a carry on I take for an 8 day trip. I pack a pair of pants for each day and at least 3 extra shirts because I always seem to get one dirty. I pack two pairs of sneakers, 3 different pairs of Crocs and 2 pairs of flip flops. I like variety in my shoes. If I have to do laundry or wear the same pair of pants for 3 days it is not a vacation. I would not want to travel with just a carry on only. What if you buy souvenirs? Where are you going to put them?
