If they as you say are "going free" how is it not working? They completed alot of their work before the trip left the country.They still have work to do right up to day of departure and at the island making sure everyone is safe.When I run a group and get a "free trip" it still costs me $..Yeah my land and airfare very often gets covered,but the wife is not(try going without her and it would cost more in lawyer fees),food at island is usually not included,buy travelers drinks,the dogs go to a kennel @$900. for a week.I am not at my job ,so no income there.So it still costs a bit to go for "free".
