I am travelling to Los Angeles in February for a four night stay and we are staying in the Best Western Hollywood hills hotel. I have been looking at all the various studio tours that are available. Could anyone tell me which are the best ones to visit. A am a big fan of the big bang theory and I hear one of the tours visit the set. Also, is Universal Studios worth a visit? Would it be worth getting the pass that helps you avoid the queues. We won't be renting a car so will be using public transport/walking/taxis. Any help will be greatly appreciated, thanks.
