Last year we went twice. Once with a 'tour' and the second we hired a car. the 2nd trip was the best because it enabled us to leave our valuables in the car boot and then, after getting very wet, got changed! This meant that we could take food and drinks and arrive and leave when we wanted. Not sure how much the dolmus is but there was 4 of us and the car cost £23 for the day so well worth it. (we had the car for more than 1 day, but that's what it cost per day - I'm waffling! Sorry)
