I think people should really consider their guests when arranging invitations. We were invited to a family wedding quite a distance away.
I was invited to the ceremony and meal, my children were wanted at the ceremony and evening do.
Obviously, we'd all go together - so they'd have to 'get lost' for the afternoon and find somewhere to eat out. I'd have to get home by train.
When I explained the difficulties this created, it turned out that I was expected to babysit the grandchildren all evening too!
I declined - but the arrangements were changed as a lot of other people had also declined.
In the end, everyone was invited to everything. I still left early to get home by train, though, as I wasn't happy to babysit. The children took turns to look after the grandchildren.
