Dominick the tour guide was 5-star A+. He gave amazing details about the Island and was talking almost non stop from the get go at 8am. We arrived back at our hotel at 9:30pm. Dominick knew the Island like the back of his hand and gave unbelievable details about little things - fruits, veggies, plants, coffee, history, lava, volcanoes, and what have you. If you ever visualized an ideal tour guide, it was Dominick.
But the tour itself was ok. Definitely expensive and if you have a car and 4 people, definitely do it on your own. The downside is you might not get the nitty gritty details of the Island. But you do save a lot of money. If you wanted to just the volcano then the tour is a total disappointment for the kind of money you will be spending. If I were to do it again, i would go on my own. Then there is no Dominick, but you save money. You pick.
