I would never travel with just a debit card, like others said. So many places put $ holds on cards (hotel, car rental, restaurants, gas/petro, etc) that unless you have $$$ in your account, you could exceed the balance of your account. I also would not want my only source of funds to pay my other bills to have the potential to be compromised and inaccessible.
Offshoot question...those of you with minors who have traveled abroad without you, how did you give them money? Back in my day it was of course traveler's checks. DD1 will go on a European trip with school next year when she'll be 16. I hadn't thought about spending money until just now.

Gluten free since Nov '11 after non-celiac gluten sensitive diagnosis. Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
