I am living proof that hanging on to first impressions isn’t always the best idea. When I first travelled to San Francisco in 2012 as part of a Contiki tour it didn’t do much for me. I have strong memories of drinking too much, seeing lots of homeless people, and staying in a supposedly haunted hotel. For a tour company with a slogan of NO Regrets, I certainly had a lot. I felt like I had completely missed the point of San Francisco.
