We are planning to take the ferry (preferably the Fast Ferry)
from Buenos Aires to Colonia on March 27 or 28 after having flown into Buenos Aires from Australia on 26 March (arrive late in the afternoon)
A few questions:
At that time of year would we expect be able to just arrive at the ferry terminal and buy tickets to go on the same day or should we book the day before?
Is it possible to book tickets somewhere other than at the terminal - for example through our hotel or at an agency (English- speaking)?
How much before departure time do we need to be at the terminal?
