If you have a destination wedding you don't get to be hurt when people say no
A destination wedding invite is asking somebody for 1,500 to 4,000 dollars and most of the annual leave they get in a year. Ask away, people say yes all the time and have a great time doing it. But I have now watched 3 separate people decide their friends "didn't show up for them" when those friends had 12 days of PTO, a car payment and 2 other weddings that same summer.
What was anyone supposed to do there, remortgage?
And nobody ever says the real thing out loud. You never once hear "it was too expensive for them." You hear "I just thought you'd make more of an effort," and the effort in question is four figures and a week off work.
So have your destination wedding. You have picked the location over some of the guest list and that is a completely fair trade to make. You just don't get to be quietly pissed off at people about it for the next 2 years.
