So I am booked for the Aug 31–Sep 13 2015 best of Europe tour and I see some dates are being sold out or filing fast. I am curious if somehow my tour does not fill up completely is there a certain cutoff that they will not do the tour? Is there a way of knowing how many people booked the tour so far?
Your tour will be full or very close. Filling fast means less than 10 spots left. Think it is usually 6.
My tour does not say that. I was just wondering what happens if somehow that tour date does not sell out is there a certain cutoff of people that they will not actually proceed with the tour. Say if only 8 people book a tour, will it get canceled?
In order to get the correct information, contact the tour department directly, they will be able to answer your question as they work for the company and will know the facts. I will say that you still have a long way off before the tour for people to book and sometimes they put tours on sale to get people to book a tour when they see it is not selling as quickly as they would like.
It is rare for a tour to be cancelled after customers have signed up. See Tara's comments on this same issue at https://community.ricksteves.com/travel-forum/tours/tour-minimum.
