America here we come

The family has got visas to visit the U.S. of A. Now we are confused whether to make an ambition plan to do both the coasts, or do one. While planning we came across some good travel sites which can be used for planning a trip to America. My favourite is tripadvisor.com
Then come a host of sites like expedia.com, hotels.com and orbitz
While on visas at least 2 families I know, other than us, have all got tourist visas this month from the US embassy in Delhi for 10 years.
As for tickets, We got a good price from Etihad Airways while Air France is also giving a good deal with a stopover at Paris.
