No matter how popular a tourist attraction is, your enjoyment of it will still depend on the circumstances you saw it in. For instance, I was very impressed when I visited Buckingham Palace, but I had a hard time getting excited about watching the guards out front.
Why? Because it was both cold and raining really hard and I got hassled by a guy who told me, "You are stupid. Very very."
However, I'm sure my tune would change a lot if I was there during the beautiful day when this impromptu show happened.
