Amsterdam remains my favorite city although it's popularity as a tourist destination is increasing, even in the off season, which makes me enjoy it less due to the crowds everywhere. So it was nice to walk around while everyone else was still asleep.
On one hand, I'm glad more people are getting to experience European destinations but cities like Amsterdam and Venice and Paris and even less-well-known cities like Dubrovnik are starting to suffer under the strain of coping with so many tourists. Venice is talking about limiting the number of tourist who can enter per day. Dubrovnik put a limit on how many cruise ships can dock each day (although that just made the cruise companies go to larger ships). I don't know what the answer is. I know it's not a simple solution.
