We will be arriving in London on Sunday for our first trip outside US. Our travel agent said not to mess with traveler's checks...charge everything and go to ATM for daily withdraws of cash. When I mentioned this at my bank, they said it would be very unwise to be dependent on only electronic means...they recommended traveler's checks. Now I'm not sure who to listen to. If I get traveler's checks, do I get them in $ and exchange them when we arrive or get the traveler's checks here in pounds? Will it be cheaper one way or the other? My other question is how much should I take out in traveler's checks? Providing my credit card doesn't get demagnitaized or something, I should be able to pay for most everything by credit card, right? I'm thinking I would just need cash for tipping and maybe cabs. Any advise would be much appreciated.
