If your card has a foreign transaction fee then I would look at getting a different card. I used to have ONE that had no fees and now 3 more have joined the no fee group.

Also...in MANY years of going to SXM I have NEVER used a Euro....I have taken them out of an ATM but for a future trip to France just to have when arriving. One to one if available with USD or CC if not is the way to go....
