Europe, the old continent.  To Europe you go for the cities.  Yes, Europe has beautiful nature but you will find more beautiful and more spectacular nature anywhere else in the world.  But nowhere in the world you will find that many different cities, that old and well preserved.  And if you like art, Europe is the best place to be with the most and most diverse museums in the world (didn’t check that but I’m sure it is true). And last but not least, we can argue which continent has the best food but the best drinks are from Europe.  For beer, wine, whiskey, brandy, port, etc. there is only one place to be.  Cheers.
