In talks with the guy at Cranham, it will probably be there, he's away will the start of Nov for the definitive answer but it definitely look like it can work.
I've also been talking to the site in Swansea, but cost and logistics is sticky on that one, £750+ just for loos to be brought onto site... Bit of a mare...
Still looking at a few other sites as well just in case, that's where we're up to at the moment though and those dates of 14-20th are still good.
Sorry it's not all set in stone already, I know it's a hassle for people trying to make plans.
