With all due respect, I believe that the phrase that you are looking for is "bite the bullet".

Back in the days of the US "old west", before there was reliable anesthesia, the story goes that when you were having a painful medical procedure, you would drink a shot of whiskey and then put the soft lead part of a bullet between your teeth and bite down to manage the pain. So, "bite the bullet" basically means to "suck it up" when dealing with something unpleasant.

On the other hand, "eating" a bullet is more recent slang which describes committing suicide by putting a gun in your mouth and pulling the trigger.

$700+ per person is definitely an unpleasant proposition for something as mundane as a boat transfer, but I don't think that very many people are going to kill themselves over it. :-D
