Can you suggest where is the best location to spend summer vacation?

I love Washington, DC! They have lots of museums, cool restaurants, clubs, bookstores, a zoo. It's perfect!

The best beaches I have been to are in the Seychelles. I have also been to the stunning islands in the South Pacific Ocean. French Polynesia has some gorgeous palm fringed beaches but it is expensive. The Cook Islands and Fiji also have stunning beaches. Samoa is the place that I liked most with its interesting culture. I was lucky enough to meet a village chief. I loved walking in the rain forest and seeing a Polynesian pyramid. There were fruit bats flying around. I saw blow holes, lava fields and then when I went under water lovely coral and colorful fish. I think that you might enjoy an adventure like I did, a safari in Kenya. One of the best trips I have done was to Mexico, Belize and Guatemala to see Mayan ruins and a cave adventure. I stayed in a tree house. I hope that you will go traveling and find some fantastic places that you will find relaxing.

I am a Chinese and LuShan is one of the best summer resort in my country and the spending for there is not too large, enjoy yourself and let the hot air alone.

why dont you travel Vietnam? natural mountains, beautiful beaches, history places, famous HaLong Bay , etc
