Weddings can be as much of a chore/faff for guests as the bride and groom make it, IMO.
I think people can be bothered going to weddings, providing there's not a huge expectation of expense and outlay of time.
What I mean is-if the couple expect all their guests/certain guests to stay over at a hotel, pay for travel and drink, outfit, potential childcare/pet care, gift alongside giving up annual leave at work-it can feel like a complete chore and even a drain to attend it.
I'm not saying couples shouldn't get to have the wedding of their dreams-but expectations surrounding guests should be adjusted accordingly. If a couple wants to have a destination wedding abroad-they can't be upset when people can't attend, for example.
I've seen some people expecting their guests to spend all that it takes to get to the wedding-including hotel stays etc and still expect a pricey gift/high amount of money on top of that.
That, for me, is where the chore/faff/drain comes in. I think some people could learn to rein in their expectations on their guests and understand that whilst their day is very important to them (and everyone would wish them well and be happy for them) it's often not the top of everyone else's priority list and that that is OK and normal.
My DB recently got married and boy, I was glad when it was over. It was a wonderful day and a lovely ceremony, but the drama and faff leading up to it, and the expense of staying factored in, ended up grating on me and other people. They did really well with the wedding, but I sometimes think when there's a big outlay of expense on the couple's part-there's pressure to make the day absolutely perfect and that can mean the couple placing unreasonable/unrealistic expectations on their guests.
