I agree that Monaco is a city/country full of money and wealth, however, if I were rich, I don't believe I would come there for vacation (those who need to show off the wealth they have come here rather).
I plan to write posts in the next few days about the places I liked the most in the region I visited and where I would probably prefer to spend my days, whether I was rich or like now (when I'm not)
