It's on a Sunday. We'll have to travel by train and we'd normally stay overnight but it's a (primary) school day the next day and I'd rather my son didn't miss it.
The ceremony is at 1pm and I'm a bridesmaid. It's an informal thing. Think pub lunch rather wedding breakfast. There isn't anything planned for the Monday.
Would it be unreasonable for us to leave at say 5/6ish? We can get the train and son will be in bed by 10ish, he will probably sleep on the train too.
On the one hand I feel rotten even thinking about it but realisttically my son will want to go to bed by 8ish so that means husband will leave with him and I won't know anyone other than immediate family so probably won't stick around much later anyway.
