my wedding was scheduled for august 21 and we postponed it pretty much immediately in april once we realized there was no way we would be able to safely have 65 guests, including parents and grandparents, in one place this year.
on the other hand, my stepsister still has her wedding scheduled for july 4th despite the province having a ban on gatherings of more than 10 people and a requirement for everyone travelling in to quarantine for 14 days after arrival. she also has no intention of doing a web broadcast, she just seems to be hoping that there's some surprise announcement in the next week or so that the regulations are lifted and all 75ish guests will be able to attend just like in normal times. the entire family is trying to get her to see reason, and she will soon enough (she's not stupid but we think that she just wants to be truly forced to do it so that it doesn't feel to her like she made the decision to postpone). it's not a matter of deposits on anything either because it's being held at the home of a family friend.
but even if they did make that announcement that everything could go ahead as normal there's no way i would attend any wedding, family or otherwise, in a time like this. it would be irresponsible and selfish to put our parents, all of whom are over 60 and at least one of whom is mildly immunocompromised, into a situation like that without some kind of mandatory testing in place.
