Venice pass

I am highly doubtful that pass would be a money-saver. You need to make a list of the places you will actually go to (not vaguely be interested in but not have time for). Much of the joy of Venice comes from wandering around the back canals, not packing your days with a bunch of pay-to-enter sights, so you may not find yourself going inside all that many attractions. There aren't that many sights in Venice for which buying tickets ahead of time is recommended, so that long list of covered museums mostly represents places for which you could make a last-minute decision and just go.

I looked at the pricing of some of the optional add-ons and found them to be marked up, so I am guessing the basic pass is also overpriced.

• They're charging an extra 1 euro for the Guggenheim and calling it "Fast Track" entry. Guggenheim tickets are timed, so I don't see an advantage to a fast-track ticket even if it is somehow different from what you could buy yourself on the museum's website. It's good to buy the Guggenheim ticket ahead of time, because there can be a bit of a line there, but the museums doesn't sell out weeks ahead of time, so it's not much of a problem to score tickets.

• They're charging 39 euros for a two-day transit pass. You can buy that yourself for 35 euros.

• They're charging 55 euros for a three-day transit pass whose regular price is 45 euros.

• They're selling a five-day transit pass for 75 euros. That's something not regularly sold, as far as I know, but you can freely buy a full-week transit pass for 65 euros.

• They're charging 28 euros for a ticket to St. Mark's that doesn't include any of the add-ons you might want to include (museum/loggia, Pala d'Oro). The official website sells simple entry tickets without those add-ons for just 10 euros (adult). Online tickets to St. Mark's do sell out in advance, so perhaps that 28-euro ticket would actual mean avoiding a 30-minute (approx.) line. I'm not sure.

Wow, thank you for all your detailed information. I have found that there are sites that come up when you look for official that do seem like you are on the right one.

Yes. It's the Wild West out there. Sometimes it helps to include the word "official" in your search string, but you still must have your wits about you, because all sorts of links you do not want will still show up. Official websites usually have a lot of background information--upcoming exhibitions, past exhibitions, etc. That's one thing I look for.

The only official passes are summarized in this resource.

Anything else claiming to be "official" isn't truly officia. I wouldn't necessarily call it a scam, but it is misleading.

And yes, acraven provides a very sharp and accurate analysis of why these passes, in particular, aren't that great value.

Go to https://www.veneziaunica.it/en. That is the official site for info on transport etc. They also have posta about interesting places to go and some brief self guided tours too.

Thank you
