Well saturday should be fine, as long as Alice is chill with it, but moving it earlier on sunday would be okay as long as everyone is able to make it.
Though there's always the whole unexpected working aspect to me (weather-based, most of the time), so if it's too early on sunday then I might be finishing up work and can't be there for a while.
Doesn't help that apparently I work the always shift now. 7/7 days of work this week, jesus. I'm dying. 6:30am to 8:30pm, I'm fucking dead.
