We always get some Euros before we leave home. We order them from our regular bank (Suntrust) but I know in some areas the banks do not do this, so just call yours to find out.
We usually bring a few hundred with us (we're a party of 2) to begin with and then we use ATM's in Europe when we need to get more currency. I would advise against doing currency exchange in your airport at one of those booths, it is an expensive way to do it.
Even if you're not a big shopper, you'll need Euros for street food, restaurants, taxis, tips, museum/site admission, etc. so it can add up.
Speaking of ATM's in Europe....this is something I always do before I leave the country & I wanted to remind everyone to put it on their to do list:
Call your bank & credit card companies and let them know the dates & countries of your travel. If you don't they may suspect fraudulent activity and cut off your card while you're abroad
Hope everyone is having a great day!!!!
