Me, I like Mexico because of its beauty, culture, food and people. I am also a history and pre-history buff, so it has a special attraction for me. It has extraordinary diversitiy of topographies and climates. It can be as urbane as Mexico City or as exotic as the jungles of Chiapas and indigenous highlands of Michoacan.
Because it is close and because I know how to stretch a peso, I can visit more often and for longer periods of time than other destinations. I was in Monterrey, Nuevo Leon this month by car. Next to Jalisco in May, with a round trip ticket from Phoenix for $191.
Bangkok Thailand, at Sukhumvitt street at 2 AM. The craziest place in the world (I mean it in the best possible way). That place is really awesome. Is it the weather? Is it the booze? Is it the drunk crazy girls ( half of them may not be what they seem). Non the less, if you want to mingle and have fun with no prejudice among people from all corners of the world then now you know what's your next destination..... If I ever find a job over there, I would jump on it with no hesitation and would retire there while drinking to my death. What a way to go that would be !!!!!
Good question. I have an odd answer considering I'm an atheist. I really enjoyed Israel. The architecture in old Jerusalem was quite interesting. I also love wandering through old churches. (Yes, I know?) The view from the top of Masada is breathtaking and floating in the Dead Sea is a cool experience. Lots of interesting museums and Yad Vashem is definitely worth a visit.
I guess it depends what you like to do on vacation. I like to explore locations of historical importance and learn things. It's my thing. Too many countries to see and so little time.
