I'm not sure that we actually locked anything down - it would probably make sense to agree something sooner rather than later though. (I have already broken the news to my parental that I will be sloping off to travel in the TARDIS. She didn't seem entirely surprised).
I think I'm going to have to drop out of the experience. I'm hearing that they herd you round it in a certain time and I don't think my legs will be up to that. But I'll come and meet you in town that day if all is well.
