It's about as bad an experience as one could have, basically a scam.
Samuel Li, the tour operator, texted me asking me to meet earlier, but I couldn't, to which he replied he'd see me at the original start time of 7:30. I texted him when I arrived, but he never heard back. I waited a half hour, and he never responded.
I put a refund request into TA/Viator, shared the texts below. I also asked for the uber expenses as I had to take one to meet Sam. They denied both a the very least they should refund the tour, the operator was a no show after confirming he'd be there.
He also ignored both my texts after I arrived at the designated meeting spot (see photos). DON"T BOOK THIS TOUR.
