My wife and I went there several years ago to fulfill a silly goal of going to all 7 continents in one year.
We took a cruise and paid about $7000 each. You can also fly there on charter flights from Southern Chile.
The views are beautiful, but perhaps not breathtaking. We stopped off on land one day to see the penguins, but one thing that fails to make the brochures is that the penguins smell incredibly bad because of all the manure that thaws out in the sun.
