ACTV has just hiked the vaporetto ticket prices in time for Carnevale.
Basic, one way, non-Grand Canal trips, now cost 5 euros, up from 3.50 euros. That's pretty major.
Day passes go up too (10.50 euros from 12.60 euros), but remain the better deal.
Of course, for gamblers, there's always the Free Vaporetto Dance.
