You are right in surmising that our California and the Golden West tour for solos will have an identical itinerary to our "standard" tour (it should be going on sale in the coming month or so). Whilst the itinerary has been improved for 2020 (have you seen the new itinerary on our website?) the number of nights we stay in San Francisco remains 2. I can appreciate you may wish to see many more things whilst there, which is why there is also the possibility of purchasing the tour as a "land only" option, where you get a discount on the price of the tour but buy your flight tickets independently. Since the tour ends in San Francisco you can therefore decide to stay as many extra days as you wish and fly back in your own time (perhaps stopping off in New York or somewhere else along the way).
I hope that is of interest to you, and if so then please call our reservations team when the tour goes on sale to discuss your options.
