I do not see much, if any, difference in this cruise and the cruises that visit the South Pole as it relates to rich people seeing something that the rest of us peons can not afford. These people probably support the "global warming" movement, yet do not want to give up their luxury lifestyle which consumes vast amounts of carbon producing fossil fuels. (see: Al Gore, Leonardo Dicapprio)  In late December of 2013 a cruise ship got caught in the ice near the South Pole and the first ice breaker sent to rescue it got stuck in the ice also, so a second ice breaker had to rescue both ships. I doubt that those people paid for the rescue efforts.
