Venice airport bus and vaparetto tickets

They are easily available so I don’t see any need to worry now.

if you buy in advance you get a voucher that you have to exchange at the same place you buy the pass at the airport. There is no reason whatsoever to do that - you take 2 steps to do something which takes one step.

Agreed. I did buy the ticket in advance, but noticed that I had to exchange a voucher for a ticket at the same place I could have just bought the ticket in the first place. Don't bother with advance purchase.

Depending where you are staying, you may prefer to take the Alilaguna boat from the airport to your hotel, instead of the bus. MUCH more charming, and a lot of fun.

We've done both. One time upon arrival one credit card wouldn't work but another did, so not a big deal. By purchasing in advance, you do avoid the possibility of encountering a malfunciton as we did. Regardless, be sure to check with your credit card (and ATM card) issuers to see if a travel advisory needs to be put on the account. Some do, some don't, and some banks are so big they give conflicting advice.

As darrenblois wrote , taking the alilaguna is a substantially better way to reach Venice and actually price would be the same as for the bus. Unless you go to Mestre the alilaguna boat is a more straightforward way.

A water taxi may actually make sense if you are in several persons but anyway it is a more expensive alternative,

Getting to Venice from Marco Polo Airport. [Make sure you have seats on the right/starboard side of the aircraft, for a view of Venice as you arrive]

Do take a look at your hotel website – there may be info there. Otherwise,

1. Water taxi will get you close, maybe to, the door of your hotel. Can carry about ten people, will cost about €140 for the boat. No need to book, taxis are waiting at the Marco Polo dock.
2. Shared water taxi. Minimum of two people. Book in advance, wait at the desk in the terminal for the others sharing the taxi. Costs about €30 per person. Google “shared water taxi Venice”, use the venicelink dot com web site. Will get you to a vaporetto stop near your hotel.
3. Alilaguna ferry, as per below.
4. Bus to Piazale Roma, then walk to your hotel, or take vaporetto to the nearest stop. Buses leave from the outside the terminal, tickets at the machine.

Water transport in Venice.
1. Gondolas. Only for pleasure, not for transport. 90 euro for half an hour for the boat, more for evenings.
2. Traghetto – big gondolas, two oarsmen, about ten passengers, for crossing the Grand Canal. Found at Rialto, San Toma and a couple of other places. Cost 2 euro per trip, can save a heap of walking.
3. Water taxis, which are like a floating limo, costs to match.
4. Vaporettos - ACTV. Are like a floating bus, operate on a bunch of routes. Get the app Chebateo for routes and schedules. Vaps do not service the airport. Vaps are not water taxis.
5. Alilaguna ferries, service the airport, run from Marco Polo via a bunch of stops to the main part of Venice, Murano and Lido. They stop at some, but by no means all, vaporetto stops.
