It ready depends on if the guide wants to just do it. Book it and see if it gets confirmed, The guides rely a lot on tips.
Ours was, by accident. No one else had sighed up for that morning.
Possibly. However, unless you signed up for a private tour, a tour operator typically has the right to cancel a tour if the number of registrants is below a certain number. As a result, the tour operator typically has discretion to proceed with the small group or cancel. I don’t have additional detail for this particular tour.
if you want a private tour, i think they will accommodate that request. we had 6 people on our tour. i don’t recall reading anything about a minimum of a certain number. i believe there is an email for questions. sorry can’t be more help.
