On our second day in Tallinn, we headed across on the ferry to Helsinki, Finland. It was super easy, having bought our tickets online before we left for Estonia. On the day it was just a case of simply heading down to the port, which we had checked out the day before so we knew where to go.
After fighting our way through the queues to get on the ferry we then saw everyone run off, people were upstairs, downstairs, in the bar, in the restaurant and the window sills. It soon became clear that seating was limited as after 10 minutes it all settled down and many people were sitting (or sleeping) on the floor.
