Ain't gonna happen. The pre-Pesach wedding rush isn't getting cancelled, or even dialed down. Unfortunately...
We can have a wedding rush with smaller crowds. Encourage people not to stay long. Test temperature at the entrance (limited benefit, but still something). And since weddings aren't like engagement parties, it is possible to suggest that attendees get COVID-19 tests within 72 hours.
A relative just had a wedding two weeks ago at Razag, quite a few people are now sick with COVID-19. A friend is scheduled to marry off his son soon. He and his wife are sick with COVID-19 after attending an engagement party which was apparently a super-spreader event.
