We were on that sailing as part of the Grand South America cruise. The tender was not going to cost anything. Don't know where you got the idea there would have been a charge to go to Ile Royale, had we been able to make the stop. All tenders, everywhere, were never a charge. The $180 was for an optional ZODIAK outing to neighboring Ile Saint-Joseph. No one is allowed on Devil's Island. In the end, rough seas prevented anyone from going ashore.
