We leave for London tomorrow morning, and I'm second-guessing myself... I plan to bring 2 separate Visa cards; one has a chip, and the other has no foreign-transaction fees. Any reason to bring a MasterCard [with chip and with printed number, not embossed] in addition? Are there places that might take MC but not Visa, or places where the flat card is more usable?
Of course, these are chip-and-sig cards, not chip-and-pin. Sigh.
We are very much looking forward to our trip despite the various attacks; keep calm and carry on!
Thanks for any advice-
