Spent most of the day finalizing my grand scheme to have (up to) 100 guests setting off on 8 tours simultaneously around the building. I think it's going to work - very much inspired by the original round-robin tours from TheOldPlace. It's just a question of having 8 different starting places and at least 8 'stops' we can all move round in a grand swirling dance. Some have likenened it to a military operation and been very impressed with the colorfully marked floorplans I've knocked out together with individualized tour scripts. But it doesn't feel that clever, just a question of rather retentive attention to holding 80 locations and movements in your head.

And there's plenty of potential for it all to go horribly wrong!
