Just got a save the date for my husband's cousin's wedding. It is on my son's 3rd birthday and is a destination wedding in another country that does not speak English. It will take about 18 hrs to get there including 2 layovers. Everyone will have to travel to this wedding as no one invited lives anywhere close. Just feel as though this is quite a lot to ask of everyone and I know he is only turning 3, but I look forward to making a big to do out of his birthday. Would it be horrible to decline? Groom is my husband's first cousin.
