Assuming both provisional guests turn up for both days and all the Ummers turn up, we've got 13. No ummers and no provisionals make 7 (because Blacksheep is piggy-backing with one of the provisioneers).
Which is why I need to know ASAFP - it's the difference between me spending £15 tomorrow for stuff and me spending £100 tomorrow for stuff.
I also know the habitation status of 8 of the 10 confirmed & provisional attendees, but not the other 2 (Mark_T; homeforsummer) - they need to contact Milford Cubicle, again ASAFP, for details of local sleeping parlours, along with the 3 undecided, unless they have already sorted accommodation on their own.
I shall start PMing the confirmed with the house postcode towards the end of the week.
