Before finally settling in to live in Thailand two years ago, I did my homework and visited every SE Asian Country. Except for Saigon, which was a mess, I liked VietNam a lot, especially the beach town at Nha Trang and the nearby mountain villages around Dalat. Cambodia very beautiful, very cheap. Myanmar poor and a little scary, Lao too chaotic for my tastes. Thailand won hands down. Best infrastructure, best food, most welcoming atmosphere, most variety of landscape.
I think I'd like to visit Indonesia the most
Difficult one... In overall I'd say Thailand, but the Philippines is getting more and more interesting the more I get to know that amazing country.
My country Vietnam is the best for me.
Burma/Myanmar for off the beaten track. Not much of a clubbing scene but you can get Guinness in a gay bar in Rangoon.
many people like Thailand but I don't know the reason why
In no particular order, Indonesia, Thailand, Myanmar, Laos, Cambodia, Vietnam, South Korea & Japan.
Singapore is pretty good attraction in Asia where unique culture outstanding beauty with plenty of popular destinations are located which attract tourist and visitors comes from all over the world especially for Sentosa, Singapore Zoo, Universal Studios, Chinatown and Boat Quay are the main tourist’s attraction.
Of course my favorite country in asia is philippines, home of the pound for pound king Manyy PAcquiao.
