What is an ideal amount of cash to take to Europe?

I'm going to countries which use the Euro for 12 days and countries which use the Pound for 7 days. I am taking a credit card but how much of each currency in cash would be good?

What is an ideal amount of cash to take to Europe?
if you take you credit card you dont really have to decide. It's hard to say, the prices are different in every country, e.g. in Germany you can get a really nice meal in a restaurant for 15 euro, in Spain or France is more expensive, than again Poland or Czech Republic is cheaper. Which countries are you going to and do you plan partying a lot?





I'll try giving you examples: Netherlands, Belgium, France: a 0,5l bottle of cola around 1 -1,50 euro, candy bar 1 euro, hamburger in McDonald around 1 euro., maybe a little bit more. I'd say 30 or 40 a day would be just fine. UK 30 Pounds a day, Ireland is in Euro zone and a little bit more expensive then the other countries.





Hope that helps!
