WE said we were old blues and the Security guy said it was fine for us to wander around, as long as we didn't go in any of the buildings..
We ended up down the Lake and found home-brew bottles we had left there over 20 years previously!!
Basically, if there is a security guy on duty, chances are, he'll let you wander about.. The whole school is covered by CCTV now.
That's our experience anyway.. We found it more fun to revisit old smoking/drinking haunts than to wander the school anyway!!!
