Dp and I have been invited to a friend's wedding in May. The invite requests cash for their honeymoon rather than presents as a gift. We're more than happy to give this but what we're stuck on is how much to give. For context they're very good friends of dp and we see them 2/3 times a year whenever we are in their country. I'm happy to default to dp as they are mainly his friends but he says he has no clue and would appreciate any advice
