Sorry but- the tour doesn’t leave the meeting place til 9- even thou everyone in our group was there. You really don’t have a different lane to board the ship- you have to nudge your way thru the crowd to follow your leader and it is awkward. The ferry finally left at 10. Vivian tried her best but hard to hear her and if your group doesn’t speak English her directions were not followed! So just buy a ferry ticket and go on your own- very little value - very little “tour”
