Ah, this might also be of use:
Not sure if that’s accessible for you, @Spondes? (apologies for hijacking your welcome but hopefully you get a meetup out of it! 
)
If it’s on a weekend, for me, a couple days notice? Anything more than that is fairly easy; for weekdays maybe a week’s notice - having to burn through unspent holiday at work so got a week off per month til April so going to do some research into the correct way to pray to the sun gods for weather while I’m off! Weekend preferable still though
