Bei einem Aufenthalt von mehreren Tagen(wir waren 5 Tage)in San Francisco kann ich den City Pass auf jeden Fall empfehlen.
This pass is an excellent value. The transportation pass is great because the cable cars are $5 per ride and you can ride, cable cars, street cars and buses free for 7 days with the pass. The major museums are also included as is the aquarium and a short cruise from Fisherman's Wharf. I would highly recommend this pass. Just a note, when I went to exchange my voucher I had to insist that my printout from ISANGO was a voucher. They expected it to have a bar code on it. After reading it over they apologized and accepted it no problem.
1st Time using Isango ,But it won't be my last , Had a Great Time everything as advertised :)
