We like to keep it intimate, so our maximum group size for any tour is 30 travellers. Better yet, we often send tours with less than 30 travellers, with our average group having only 22 folks on board.
Many other travel companies travel with groups of 40 to 60 people. The big benefit to a smaller group is it takes less time for the group to do things like get on and off of the coach bus, do hotel check in, or gather up after an activity.
There is a minimum number of travellers we require to be able to operate our tours. The number we need varies from tour to tour, but typically we need 16 travellers booked by the tour’s final payment due date to go ahead with the tour.
