Now that the Bank of America / Santander partnership is not so beneficial (as of Nov 8, it appears as though BofA is charging a 3% forex fee), I'm considering other options.
Has anyone had actual experience using a Fidelity Cash Management account in Cancun? They claim that they refund all ATM fees and only charge a 1% forex fee (which, obviously, should be better than 3%). I just wonder if anyone has actually done this and find that it works well. I'd hate to rack up a lot of ATM fees only to find some glitch in the system.
