I went to a wedding last week. Lovely country house venue, everything under one roof. The ceremony was at 1.30pm. By 1.50pm, it was finished and we were in a room milling around. And then we had to wait around until 6pm when everyone was supposed to go into dinner, but it was nearer 6.30pm. It was pissing down outside and there was nowhere to go. We did chat with lots of nice people, but there was literally nothing at all to do but drink all afternoon. And at £14.50 for two G&Ts from the bar, that was limited too!
AIBU that maybe it would have been better to get married at 4pm in that case? Or provide entertainment or something?
