Hi Ed S! Good to see you around again. It's been awhile!
All the answers to your questions are likely found here already. Look up and to the right, find the SEARCH link and click on it, then enter ATM as your keyword search and you'll find many MANY postings about ATM card usage, traveler's checks versus ATM, exchange rates, commissions, I think just about everything.
Last month while in Madrid is exclusively used my ATM card at ATM machines for all my cash and didn't even cash any of my traveler's checks. Lower commission on ATM exchanges than on traveler's checks exchanges. I think mine was about 2%, but it depends on your company. Call/write them for their international exchange rates. Good luck!
Saludos, MadridMan
