From the first working day in January, you are able to book the busses for that year.
With this in mind, and how busy they get, it is always worth getting in there as soon as possible.
Knowing we were unable to get them for gathering, if there are any other events this year we wish to use them on, it may be worth getting dates sorted soon, and getting them booked. (We have already secured 2 for Gorge Walking
