I just wanted to post this to let folks know that they should be very careful to build in a fair bit of slack into their budgets this year because of the widely fluctuating value of the Euro. Although it is currently at $1.38/euro (interbank rate, so the rate you'll get will be 3% worse or more), just a week ago it was $1.48/euro.
Beware and check your accounts when on your trip to make sure of the rate you have been getting. These fluctuations will likely continue for a good deal of time given the current global economic instability.
