in the case of showing on the calendar and then cancelling- well, it's annoying, but here in the real world, a concert or jam night can be put on the calendar months in advance and then be cancelled or delayed because someone is ill or it just doesn't work out.
And I guess I just don't understand how people feel pressure from the 180 day availibility thing. Maybe I'm just wired wrong, but if I wait til, I don't know, 90 days out, and I can't eat at BOG after all, I'll just book something new or eat QS. I won't collapse into paroxysms of grief over something like that. At most, I'll feel a bit wistful as I walk past. If I was working as a phone CM and someone told me that if they didn't get that ADR Rez, their whole trip would be ruined...well, I'd certainly try to find a spot for them but the whole time I'd be trying not to laugh
