I highly recommend the city pass. We took advantage of the bay cruise, visiting the aquarium and rode lots of buses and cable cars. And all at our convenience. It was awesome. We did use some of the other coupons in the book and all in all well worth the money,
Useful for getting about city, also comes with free access to some attractions.
Handy to have especially for public transport.
The museums on the pass are good and worth visiting.
Allows quick access to all museums and handy if there for the full 7 days the pass is valid for.
