What does the Rolling Venice card offer discounts on, aside from the 72h vaporetto pass? Thanks!
The Rolling Venice card is for those 14-29 inclusively and if you buy it, you can get a discount on a card allowing 3 days of ACTV boat and bus travel in the city (not including the airport) as well as discounts on admission to city museums.
Is there a list of the museums and businesses that offer deals with this card?
It seems to be a bit of a secret. They're listed in the Rolling Venice Guide which they sell for 4 euro. A destination expert on Trip Advisor said you just need to check the websites of individual museums to see what the discount is. The expert also said (and I quote) "(here in Venice those who manage tourism and transports websites do often not have a clue about good communication, you know...)"
20 euro for a 3 day transport pass (plus the 4 euro registration fee) is half the normal price of 40 euro, so if you qualify, its a pretty good deal.
