We arrived in Buenos Aires 3 days before setting sail which gave us ample time to enjoy this fascinating city. We stayed in a very lovely little hotel in Palermo Soho. The location turned out to be quite a distance from the city centre, but the inexpensive cost of taxis made the trip downtown less of an annoyance.
Take some time to spend in Buenos Aires if you haven't been there before. It's multi faceted and interesting.
On the day we embarked the ship, traffic from downtown to the pier was absolutely painful.
