GerryM, I think you are confusing my preference to use a credit card with a my fear of a lack of consumer protections. That is not the case. If my debit card was hacked, I would have the protections you speak of. For me, I'd much rather use the credit card and earn points, and if either card is compromised, I rather deal with the ramification and the corrections with money that I don't own (credit card) than money I do own (debit card) and money that I also rely on to pay my mortgage, utility bills, etc. Not sure if you have an equivalent institution in the UK, but my debit card is through a credit union, and I'd much rather deal with a conglomerate (i.e., Capital One) than my little credit union if anything goes wrong money wise on international trips. I'd also much rather lose my credit card than my debit card.
For travel, I suppose my ultimate advice is use whatever form of card you would use at home. Additionally, use your debit card to withdraw cash at the local ATMs on an on needed basis (and if you have a card of some kind, preferably your credit card, there may not be a lot of use for cash).
