About the food thing.....I kind of agree with the guests a little bit (although they could have been less rude about it). If I am on a once in a lifetime vacation, paying tens of thousands for a two day excursion, I want to EAT! This lunch at 2, dinner at 8 or 9 thing they seem to do on this show....I would be pretty darn hungry too! Especially with all the alcohol they seem to consume on these trips, I would want some nibbles. Doesn't seem like there are ever any hors d'ouevres or snacks available. These guys all looked to be into body building as well. Muscles burn a lot of calories!
To me, being the chef would be the worst job on the boat. I know how time consuming cooking for one person can be....can't imagine being responsible for feeding the guests, the captain, and the crew every meal for weeks on end. I'm really surprised there aren't two chefs, or at least a 'sous-chef' or assistant. How can one person cook that much food?
