Kevin had an in-depth knowledge of the city and its history. He set up a comfortably paced tour that gave us a great look at the city center and we better understood its people.
Helped navigating through the busy stations without losing the group.
Alex was an excellent guide, checking regualrly if we needed a comfort break, etc. Also, he is so knowledgeable, the tour he put together for us was excellent, ticking off so many things we had on our 'to do' list that it left us time on our remaining days to explore HK at a leisurely pace.
