Expedia.co.in brings in years of international experience in India. There are wide varieties of options available to choose from as they have tie ups with all major parties involved in this sector. You can search for and book hotels, flights, car rentals, bus tickets and they officer special deals and holiday packages too. They also offer free cancellations and best price guarantee. The website itself is simple and easy to use. They have a lot of user friendly features too which are nice once you understand how they work.
But I sometimes think they take a lot of time to load search result and options. Give it a try sometime, at least to compare the prices offered by other providers.

I made a long trip to Southeast Asia this summer. I went to Thailand- Bangkok, Koh Samui, Phuket and Chiang Mai. In Vietnam I visited Ho Chi Minh and Dalat and Hanoi. I went to Cambodia and Laos as well as Singapore and Malaysia. Thanks to mydala I got wonderful deals, and through Expedia got 50%off on some hotels! I was so happy with all the arrangements.
