Mario is a pro and it shows in the little details. He immediately replied to my request with a welcome note. As the tour approached, he reached out again with advice on what to wear, the need to hydrate, and sun protection. During the tour he provided the customary water but also provided sun screen, insect repellent, and perhaps most importantly, iced towels to cool us down. He did a good job with the big details too; the tour was informative, and efficient. A very good day for us.
