I guess some of the thoughts, and maybe where I differ....
ATM/Debit card use: Not sure why people are hesitant to use them, that is what they are for. I do have a Schwab account, as well as my credit union, both utilize MA or Visa for transactions, and are protected. If there is fraud, you are covered, you may be out up to $50, the one time in 40 years I had an issue, I was out nothing. Your bank account is not emptied, never to be seen again.
Fees: I have experienced like many others, European banks are quickly adopting fees. I will be in Spain soon, I expect both fees at bank ATMs there, as well as offers of DCC.
Of course with contactless, either by phone or card, and having about 80 euro on me at the moment, I may not need to use an ATM the month I am there (OK, I still have this need to always have about 50 euro in my pocket at all times...so maybe once or twice)
