Share 'Information about Los Angeles tour for our group'

We are arriving at LAX from Australia in February 2012.   There are 2 families in our travel group – 4 adults and 5 kids. We would like to book a tour from LAX around Los Angeles to see the sights and then be dropped at 2 hotels – one in Hollywood and one in Santa Monica.   Could you suggest a sightseeing itinerary for a tour please?
