When I was on a USA tour , and the Jack Daniel trip was optional, and was one I very much wanted to do, I was extremely fed up there were not enough numbers to run it. So in the end we clubbed together and paid the outstanding people's money, and then said they had gone sick...rather than NOT go.
It really is very annoying! ...sometimes you can get to a place and do it on your own but sometimes you can't you need the JY tour bus etc....
It Would be good if JY stipulated online or in the brochure ...this needs X amount of people to run this optional trip
