Yes that Silversea single supplement is 75% on Vistas and 100% on Balcony cabins. That A&K 30% is really a great value.

Diane, there will be penguins but probably no chicks in December. The chicks are so much fun when they get a little bigger chasing their mothers for food and then when they molt they are amazing little creatures. However, better to go and miss the chicks than not go at all.

The longer voyages of 18 and 19 days go to South Georgia and are better timing for the penguin season.
Dec. 17, 2010 - Jan. 05, 2011
Jan. 02, 2011 - Jan. 20, 2011

That January 02 to January 20,2011 is the better of the two voyages.
