Hi I am planning a visit to the west coast USA on my way back from Hawaii to London in June (2013). I am planning to visit SF, LV & LA @ 6 days in each city to include tours & rest days. I have done some research and have an idea of costs for multi flights, hotels and tours. Now, I am looking for a reputable travel company )or 3 for best value) to make the arrangements. Can anyone recommend any companies? I am based in London. Many thanks.
