I kept an eye on the date for about a week before. It kept showing that it was available. I made my reservation a few hours before, and as per the website, there was availability all day long. Only to find out, a few minutes after confirming the reservation, that it was wrong. There was no availability for the whole day neither the week. A whole day planned around the helicopter tour and a charge made to my credit card that will take more that a week to clear out. No trusting the company ever again.
