.... but as I'll be sleeping with Dibble that night

, might not be practical....
The Campanile will be £40 or you could stay at the gates to Brands at the Thistle - £50 for a twin or double through
these guys or could ring to see if they have single rooms cheaper. Quietest rooms are at the back on the ground floor and they do the best hotel buffet breakfast I have ever had

. You could probably leave your trailer inside Brands overnight so should be secure (check first though).
