It's not all over yet. Rasher was suppose to have increased the size over the weekend, but hasn't yet. The last post he made said they were extending the main room and using a separate sleeping room (same as last year). Azrael hasn't paid yet either and will no doubt make some noise about it! I would keep an eye on it this evening and tomorrow evening, as it will no doubt be confirmed what's going on soon.
If the sleeping room is next to the toilets again, then I might ditch the tent idea and go with plan B, the back of my car (which you can still share if you want to Rai ). There's probably more room in there anyway. I'll still bring the tent and make my decision Friday.
