Just by way of an update:

We'll be doing tours at 11, 2, and 5 on Wednesday (with me) and Thursday (with Chris McKenna). We might be able to arrange tours at other times if there's demand.

Please sign up on the wiki or ping me offlist if you'd like to come, just so we have an idea of demand. 

This is a good opportunity to familiarise yourself with the conference venue (which is a bit of a rabbit warren!) while it's still relatively quiet.

Best,
