The city pass was well worth it! We went to almost all of the civic museums! We were not able to go to all of them because we have run out of time! It took us about an hour on some of them and at least half an hour for the rest. You have to find every place on the map so you can plan your visit better. It took us longer to find some of the places because Venice is a wonderful little maze of narrow alleyways. I have added a three day transport which was a bad idea because we only needed one day to go to Burano and Murano. The transport ticket is also non-refundable so if I were you, buy your transport tickets when you get to Venice instead, so you will have an idea of how much you will be needing the transport. I could not really see the point of buying it if you are not planning on going to the other islands because you can walk everywhere and there is so much to see along the way.
