My SIL will be 32 weeks pregnant at my destination wedding in Europe. Everyone in attendance is from the United States. They told FH and I think was a planned pregnancy. We're covering their accommodations, as well as the accommodations of all guests that are attending.
SIL has told us that it's likely that she will not be able to attend the wedding ceremony due to pregnancy. She has an even less likely chance of attending the reception. At first I thought that made perfect sense, who at 32 weeks would want to travel to Europe for a wedding! But she clarified: she'd be attempting to attend the ceremony, but they still plan on coming to Europe and spending the four nights at the hotel we're covering. They're rolling it into a larger, 2-week European vacation they're taking. Brother goes where SIL goes, so if SIL deems herself unable to attend, brother won't come either.
I'm not getting a good feeling over providing accommodations for two guests that have said they likely will not actually be attending. It's expensive for us and, to be honest, hurtful. You have the energy to go on a two-week vacation but not attend a wedding? I don't have a strong relationship with them to begin with.
Is there a way to politely say that you have to attend the event in order to actually take advantage of the accommodations? My parents are just so relieved that SIL and brother are going that they can't see how rude they're being. FH and I are splitting the cost of the wedding with them.
