We will embark in Barcelona on Nov 14th on Pursuit at Moll Adossant Terminal C.
Onward will be overnight in Barcelona an is announced to dock at Moll Barcelona (WTC).
So there is hope!
A few days ago I read that cruise ships (not longer than 250 m) will be allowed to dock in Venice port in 2027.
There is a shuttle, run by port, from Terminals A - E to WTC. It was € 4,00 one way and € 5,00 return journey in spring.
