We booked the Private, skip the line tour for the 4 of us. Our daughter didn't male it, so it was my wife and I and our son. Chris was our guide. she was AWESOME!! Filled with knowledge (told us she has been doing it for 18 years) Did the early AM tour, to beat the heat! Worked like a charm! This is a MUST DO!
I was still adjusting to the time difference and slept in so was an hour late. Thankfully someone phoned me and said if I wanted to do the full 3 hours I need to pay a fee of 60(euros) We managed to do the whole tour and didn’t need to pay a fee. Our tour guide was very polite and knowledgeable.
