I love using packing cubes and just did a 2 week trip to Greece and only took a carry on! I HATE checking bags!
Oh! Nice, I want to be you when I grow up! haha....I aspire to be a carry on only traveler on our next overseas trip. It's in December (so I'm thinking heavier, bulky clothes) BUT I am going to try.
In the meantime, I've got a few work trips coming up that I'm going to use to fine tune and practice. Those are easier, it's just a few nights.
