I've tried other India guides, but rough guides are definitely the best. My husband and I were travelling travelling South India independently in Nov of 2009. We got a prepaid sim card and booked hotels along the way using all the guides recommendations. The guide gives good background information and helps you stay out of trouble. I especially like the public transport information.
Tips:
-Most upscale hotels have to booked well in advanced in India. If your budget is under $50 you can basically walk into a place to see it before deciding. Most hotels are located next to one another so it's easy to find another one. Bargain hard, the economy has slammed this part of the world. When possible call for a driver to pick you up if you arriving by bus or train, they will do it gladly, and you won't have to haggle with the drivers or go on a joy ride.
-Drivers will take you to the places that offer the best commission. Sometimes these places are good, most of the time they aren't. It's up to you, get a cut of the commission, and don't take no for an answer.
-Book train tickets well in advance or you'll be riding in cattle car with the locals. Don't be cheap about transportation, you didn't go on vacation to skimp, every seat you hog up in 3rd class is a seat you take away from someone that cannot afford more.
-All nice stores pay $1 to the driver for bringing you to their shop, and the driver gets 10% of your purchase. Keep your luggage light and don't buy their junk.
-When in India eat Indian food.
-Be respectful of their beliefs, you don't want a tourist taking pictures of you while you are praying in your place of worship.
-Go with no judgement, don't expect it to be like home, or say that it should be like home. It's not, it's India, and it's a very special place that will hopefully never look like home.
-If you a female going to a beach, expect young men to take photos of you. There's nothing you can do about, other then go to a beach where no one else goes. Stay away from Baga Beach in Goa if this bother you. I loved Benellium Beach right next to the airport and train station.
-Bring insect repellent, if you can bring a net or racket. There is no need to take malaria pills unless you are going to be in the woods for an extended period, but most cities are just fine. UV water sterilizer can be handy. Combination padlock to bolt your own door, sleeping sacks, sun screen, & this book.
-Travel light.
