buy ferry tickets in Venice

[Mark]

Hi

We plan to visit Venice next June and I'm trying to work out if we need
to buy ferry tickets (be there for 3 days, staying at a camp site in
Punta Sabbione and getting the ferry into Venice each day) before we
arrive or if we can buy daily or 3 day tickets once we're there?

I know you can buy them before you go but have heard of problems with
getting the actual ticket once you're there. Have yet to find anything
about buying the tickets once we're at Venice or at Punta Sabbione.

Any advice would be very welcome - if I can sort this out before we go
it'll be one less thing to worry about.

Thanks

it's really easy to get the tickets when you're there. I did it all
the time. Easy.
