Approximately how quickly do the spots fill up for each of the tour dates for group journey?

There are no  such definite answers and will depend upon travellers. Sometimes groups fill  up quickly as all our groups are kept small and at other times, signs up is slow or none. The trend since last 6 years is that it’s  been filling quite quickly. A group can consist of 2 – 8 or 9 members but not bigger than that. If there are more interested members, we will form different group. Smaller group allows us to tend to the guests in personalised manner. Bigger can be overwhelming and it is invariably at the expenses of services to some guests.
