Be very careful about the exchange rates - especially on credit cards, if you take any; the additional fee - it ws 3% on my card - for the currency conversion can build up fast.
To my knowledge, Capital One is the only 'major' credit card purveyor that does not charge a 'currency conversion fee' for 'foreign transactions' (transactions done in a currency other than US Dollars, if you are from the US). There is a comparison of fees charges by various cards listed on the Bankrate.com website that has been referenced on Stretcher.com a number of times, but I just looked quickly and I couldn't find it.
The only 'foreign country' that we regularly travel in is Israel, and the hotel that we stay at and the rental cell phones that we use are charged in US Dollars. We bring lots of US Dollars with us - which (although their 'value' has dropped significantly in the recent past) are VERY acceptable at gift shops, etc. there, and in other countries, and we go to 'conversion' places that convert dollars to 'NIS' ('New Israeli Shekels') for groceries and restaurants, etc. We've never needed to use ATM's there - there's too many fees. I have no idea what the fees are in other countries, though.
I don't know what kind of places that you are planning to stay at, but we stay at an 'apartment hotel' that has a small kitchenette with a sink, microwave and mini-refrigerator, so we spend a lot less on meals than we would staying at a 'regular' hotel without such amenities.
Also, depending upon how long you are staying in any given place, most places offer a range of discounts based upon length of stay - weekly rates, monthly rates, etc., so it helps to ask, because you may find that you can stay some place for 7 days for the same or maybe even less than it would cost you for 5. It cost us very little more to stay for 30 days than it did for 19 previously.
Yours in frugality,
Miserly Maxine
