I've been to a not-so-close friend's wedding at conrad during weekday. I aren't sure if I am added to the list becos there wasn't enough people to meet the min guests requirement by the hotel. Frankly, I am surprised by the invitation, I gave $88. I've also been invited to a Chinese restaurant wedding from a very close friend, I gave $120. I think it pretty much depends on the relationship between guest and the couple.
