Ah yes... sans escort is something that's a bit tricky. We take a bit too many liberties at the moment (and will continue to do so in the name of good fun) but that's one of the things we at least have a semi-plausible explanation for. It's also a time when the streets of London aren't exactly safe either. BTW, there's also a hidden route as well, and a couple of people have found that one, so we will probably leave it as is. :)
