We are invited to a close friend’s wedding in Europe in March. Flights are purchased, hotels are booked and time off from work arranged. They just changed the date to the week before Christmas. The venue they really wanted had a last minute opening. The flights for that week are now $2800 each. (We need 3 tickets). We originally paid $850. Hotels are up by double. They are really angry at people who said they can’t come on the new date. Am I wrong if we have to cancel too?
