Both the city bus tour and Alcatraz Island experiences were excellent, with a very experienced and well understood morning tour guide. Unfortunately, coordination between Extranomical and the Guided City Tour people was not as seamless as it should have been. When we arrived in the morning, the on site coordinator didn't have us listed for the afternoon tour and I had to make a last minute phone call to Extranomical to be apprised of the afternoon check-in details.
