Sorry guys, but Paris is still the most beautiful city in the world.
Granted, before I can say that for sure, I still need to see New York City, St Petersburg, Vienna and Venice, but I don't expect any city to take the lead on all the things that make Paris great.
The architecture, the history, the museums, the parcs, the restaurants, the food, the convenience of getting from one part to the other, the variety on an overall human sized area, there is so much to do and to see, it's just mind boggling.
I am just in love with that city.
The French Alps are also an amazing destination in the winter if you enjoy skiing, but boy is that an expensive holiday now. In my books, still the most important holiday of the year (I need the snow and the peace of the mountain to recharge my batteries), but you need to enjoy the cold, skiing (or snowboarding), group food and drinking, otherwise it is not so worth it.
Closer to the Region, I have enjoyed tremendously going to Iran (Shiraz and Isfahan) and to Jordan. Be it Persepolis or Petra, the sites by themselves are worth the trip.
Sri Lanka was also beautiful, though I would not dream of driving there.
Turning to the US, Las Vegas is worth seing once because of how unreal it is (you think Dubai is over the top ?), the Grand Canyon is breathtaking, Chicago is a wonderful city, LA is mostly worthless as a city, but the theme parks, the beaches, Hollywood Boulevard and Beverly Hills make the trip interesting.
