I’m planning a surprise vacation (yes I’m American) for my wife, my son, and I from September 1 to September 12. Planning 4 days in London and 6 days between Glasgow and Edinburgh. Really want to see Filbert Way, but not sure logistically feasible. Planning to take the train from London to Glasgow. Really want to purchase a kit for myself and my son. Can I purchase them anywhere or does it have to be in Leicester? Cannot order online.
