We appreciate your comment, but we are really sad to know (through your review) there were 2 doctors in your group of 3, who instead of waiting (at the last stop of the tour) for the ambulance to take the affected customer to the hospital, you preferred to take a taxi to go back to your hotel. We understand your annoyance, since your refund request was denied; first, because when you called to our office you threatened saying that if we didn't refund you, you would write a bad review and second, because you did and enjoyed the whole tour. We are sorry you preferred to go back to your hotel instead of waiting a few minutes (and not hours as you said) for our guide, who was assisting the affected travel companion.
