Rather than bury this in an old thread, I decided to make a new post. Not a bait & switch, but an explanation from Joe Cool regarding the $50 price increase. Makes sense, but should have been provided when I tried to book.

"We charge $15 per person for a regular transfer but we have to get 3 or more people, if we get 2 more people before your arrival date then we will confirm your pick up. We couldnt take one person since we would lose that way."
