If you already have the Euros, I'd go ahead and bring them. I always find a few places that try to get around 1.15:1 or so. But, so many places now take credit cards that I use my 2% cash rebate, no foreign fee cards instead.
No real biggie if you don't bring the Euros, because everyone takes Dollars, many at customer favorable exchange rates, and only a few charging a premium.
