I would not get to hung up on credit cards unless you've had credit issues with one in the past.
A trick I have to save on FOREX fee's is to prepay a few hundred on a no-forex credit card and use that to withdraw foreign funds. It's not a lot but every penny counts. In the US you have a LOT more options that the 2-3 cards we have in this regard.
As for a debit card, isn't it limited to the amount that can be withdrawn? And what if it doesn't work? You might get into a situation (either for flights or medical care) where you've got to pay big bucks
right there and then even though you will be reimbursed by your insurance coverage later on.
I take VISA, MC, Amex and cash. Never needed any for an emergency, but should you-know-what hits the fan I'll be ready to deal with it. I also never use debit for security reasons,
unless you have a card for a separate account
just for travel, you are opening up your bank account to anyone with a card reader. I've had CC's spammed over the years but never had to pay a dime and a new card arrives a few days later. I've heard horror stories regarding spammed debit cards.
And one last thing, I use CC signup points bonus miles to pay for
all our international travel up in the front of the airplane.
