If I could give zero stars, I would.
Booked a helicopter at an agreed price. Around 2 hours before the flight was to depart, I was told by the company's representative that they had now decided I would have to pay an extra $1,000 (taking the total to $3,000). The notion of "agreed price" seems to be beyond their understanding. Duress seems to be very much in their understanding.
Excellent door-to-door service, no waiting.
