My wife and I spent 5K total to go to her sister’s destination wedding in Key West last year, shit still pisses me off. Please don’t ever have a destination wedding where flights alone cost almost 1K per person. The audacity is her sister and her husband complained about not getting gifts from everyone who went, gtfo.
I know a couple who did similar. They’d talked about a trip to the Caribbean for years, decided to combine this with a small wedding ceremony on the beach, went and then when they came back, they had a massive garden party style buffet reception for family and friends. Nobody complained and they got to do a bucket list holiday too.
