We had a port stop in LA at the beginning of October and used Sunseeker Tours for a group tour. You can book directly through the company or through Get Your Guide or Viator. We booked this tour as our cruise ship was only in port for the day and we thought it would be a great way to see the famous sites around Los Angeles. Our driver, Alberto, arrived early for pick up at the cruise terminal and we all boarded the small, air conditioned bus and left before 9 am. Alberto was an amazing guide/driver. He was very personable, had a great sense of humor and his knowledge of Los Angeles was impressive. It was truly a whirlwind tour of LA, but Alberto managed to show us all the sites in a day - an amazing feat considering how many places we visited in that time period. If you only have a day in LA, then this tour is perfect as it will highlight the important sites, but you'll definitely want to come back another time and spend a few days exploring the city in more depth.
