Arrived in Buenos Aires this morning. There were several Seaborn representatives holding up signs right outside of the exit, then we followed one of them to the bus to our hotel.
We were lucky and able to get our room right away, but if no rooms are available, they can store your luggage, so you can go sightseeing. Seabourn offers some tours in the afternoon and evening (see below), if you don't have anything planned.
We'll fly to Ushuaia early tomorrow morning (our bus leaves at 5:30 am 😱) to board the Venture.
I don't know how well the Internet works on the ship, but I'll try to post when I can! I'll definitely report our experience through the Drake Passage without the stabilizers.
