Who is in your group? (and so how likely for one to be a drop-out? :smirk
Exactly which ferry out is that? Will book a place on it and see if a cabin is also available (worst case will sleep in the bar!)
re the return, which B&B is it? Will see if I can negotiate a deal on the remaining room.
Also do you have details of exactly which tunnel train back you have in mind?
As long as it isn't a pint of Eurofizz lager, and ideally something of Fuller's, happy to oblige!
(what else do I need to book? Le Bounty, paddock passes etc...?)
