Because of the COVID-19, I ended up being the only one to book the tour on that day. Despite this, the tour wasn't cancelled, it basically was a private tour, but I wasn't charged more than for a group tour. The guide and driver, Jackie, was very kind and knowledgeable, he provided detailed information about the various places, much more than one usually hears on such tours. The temples themselves were among the most impressive ones I saw in Thailand. Overall, if you are at interested in temples, and if you have a few days in Chiang Mai, I'd strongly recommend taking this tour.
