BIL and partner have booked their wedding abroad (5 hour flight) on a Tuesday during term time. It is the week before a half term break (which has yet to be published but I'm pretty sure it will be the week AFTER the wedding). We warned them beforehand that our DD would be starting college around that time and also enquired if it was likely to be during half term (to indicate we weren't keen on taking our other children out of school). It was also pointed out that his parents wouldn't be keen on such a long journey due to health reasons and one has already said (to us) they won't be going.
They have been together 16 years and have four children of their own.
DH has been asked to be best man and DD a bridesmaid. There was definitely some surprise/disappointment when we said we would need to consider whether we would come or not. This is not a financial issue but I am not keen on taking children out of school and am also concerned about the timing for my DD starting college. The wedding isn't for another 18 months and we have said we will need to wait until nearer the time to see if we can go. My DH will definitely go regardless as he wouldn't want to let his brother down.
I don't have any problem with people getting married abroad if that's what they want but I do feel if they expect family to come (& bring children) then there should be some communication and conferring about dates in advance. Which there wasn't. AIBU?
