Truly, going to Antarctica is an adventure of a lifetime. Not everyone has the opportunity and resources to get there. The equipment, accommodation, transportation cost an arm and a leg. I would be shivering the whole time if I was there. The animals seem to welcome the arrival of their guests especially the friendly penguins. They are probably used to the appearance of humans in their habitat. The precious place needs to be protected, so yes, I agree about the rules. You made a detailed narrative of your adventure in Antarctica. Awesome!
