Our European travel style has been to visit a city, explore it thoroughly, and take a few day trips to surrounding areas. Recent trips have been to Rome, Florence and Paris. When I was younger, i spent a summer in England, with additional trips to Scotland, France, Switzerland and Austria. We would prefer to travel to Europe every year, but are lucky to manage a trip every other year on the average. I am currently limited to the following months for travel to Europe: March, April, and late October. At some point, we would like to go to England, but will probably wait until I can go in the warmer months. While many other European cities might be interesting to visit, I wonder if they simply will not measure up to Rome, Florence or Paris.
I am interested in hearing from people who have revisited some of the great cities of Europe instead of trying to see new places on each trip. How has the second or third visit compared to the first in terms of the richness of the experience? What tips do you have on making the most of repeat visits?
