4 things tourists should know before visiting Europe on a cruise, from a local
I'm from Romania and I've traveled around Europe extensively, and no matter where you're from, there are important things to do.
I've seen plenty of tourists make mistakes while traveling around Europe, including people visiting by cruise ship. It's not uncommon, especially by Americans, but I think these are mistakes that can be avoided.
It's worth it to do research before your European cruise to understand the basics. When I visit a new country in Europe, I'll always try to understand their culture more because it can be different from my own.
