Frank, a trip to Europe may involve leaving your comfort zone, but it is not beyond the capabilities of any qualified pilot who, like the OP, is taking the time to familiarise himself with the different procedures and requirements.
If he makes sure that he is legal he will find that European airspace is a professional, efficient and very friendly environment, and one operated by people who will be more than happy to help, rather than hinder.
Go for it, I say, and enjoy the flight. You will be made to feel welcome.
