It 'll be impossible to please everyone, but I think the original idea was for a tour of the U.K., so therefore, I don't see how you can miss out Scotland and Wales. But, don't forget the U.K. also includes Northern Ireland. You can obviously go too far in this and it might be an idea to still try and get in England, Wales and Scotland. Whatever you decide to miss out will get up someone's nose. You can't please all the people, all the time etc. What you could do, I suppose, is to include North and Mid Wales, the Midlands, the North East, Scotland and the North West. That would obiously hack off those in the South East and maybe the South West.
Alternatively, you could include a series of loops where people could join and leave at will. For example, Liverpool-Mid Wales-Shropshire-Herfordshire-Oxfordshire-Wiltshire-Bucks.-Beds.-Northants.-Leics. etc. all the way to Scotland and then back down to the North West. The point being that if the whole route is too long for the Mancs and Scousers, for instance, they could miss out the South East section and skip straight to Leicestershire and meet up with the S-E mob. This could go on for everybody, whereby you could miss out sections, but still meet up with the main body of the tour when and where it suited them. If the 2 guys who are worried about passing their tests in time, if push came to shove, they could possibly get a lift from somebody else and share costs. Just a thought. Also, why not think about going in June when colleges break up as the weather is usually as good as August but sites could be more freely available and cheaper. Any thoughts? Anybody still awake?
