Once, a stranger at a party imparted an invaluable piece of advice to me: “There are friends you can travel with and friends you can’t – and you have to know the difference.”

I have since learned how true this is. I know of friendships that almost collapsed because one person wanted to fill each day with activities while the other preferred a more relaxed approach. I spent a blissful week crisscrossing Italy with a friend whose travel preferences exactly overlapped with mine, but argued with another who wanted to go clubbing at 2am when I desperately wanted to go to bed.

In short, traveling with friends is high-risk, high-reward. We want to hear your tales of traveling with pals: the good, the bad, the ugly, the bachelor parties.
