I have two brothers who live in different countries both of which are a long haul flight away. Both have decided to get married in their respective countries within a month of each other. Neither have kids (we have 2 school age dc) .
DB1 booked his wedding in termtime, very expensive flight as not popular destination. Said would love us to come but understands if not. DM would love me to go. No chance of childcare so would be solo trip for me to destination I am not fussed about.
DB2 asked for holiday info then decided to book outside of holidays even though we said we wouldn't be able to bring the kids and possibly not come. Destination cheaper and more attractive. MIL has said she can look after the kids so DH and I could both go, but that would involve doing school drop offs, after school activities, walking the dog etc. MIL is a bit frail but determined.
Fwiw we can afford both weddings but could, and would prefer to, use the money for other things.
Can't decide if IABU and a bit of a spoiled brat or not?
