The excursion for the penguins is nice, but the cruise line fails to tell you that even during summertime and good conditions, you have to wear winter gear, nobody warned us, and we froze in summertime. It completely messed our experience.
Definitely worth it. The excursion with the highlisghts of Montevideo and lunch at Juanico Winery was excellent. Our guide was very good and entertaining and the visit to the winery even included a tango show
