Booked this, on the strength of what we’d seen, on Tripadvisor, and we’re really pleased we did. We used the Hollywood pick-up option and were taken to Santa Monica, where we joined our group, for the day, and our driver/guide, John.
There was a good balance of being on the move - seeing the sights/hearing all about them and having time to explore for yourself, with guidance about what else there was to see, in the area, as well as clear maps/time instructions, to ensure everyone was back at the minibus, when they needed to be.
Just to note, if you want to go into Griffith Park Observatory, at the moment, you need to wear a mask, as well as having proof of your COVID vaccination and photo ID.
