Is it rude to charge wedding party for Airbnb?

I don't think it is rude. Weddings are expensive and they are getting a great deal for the Airbnb.

It's not rude at all. You checked with everyone on their interest and their budget prior to and are covering the rest of the cost. It's not like you would cover their hotel if you didn't book the Airbnb, so you're actually helping them out which is very generous.

If they all need to stay somewhere, and you asked them all in advance, and it is optional for them to stay at the property you've chosen, then I think it's fine. I think there are at least two scenarios where this gets questionable. The first is if wedding party/guests are TOLD they have to stay someplace and pay for it -- if anything is "required" of the wedding party beside their basic wedding attire, the etiquette is that the B&G should pay for it. The second scenario is the one that gets even more questionable in my opinion, it is when the wedding will be held at the Airbnb (or another site like a Bed & Breakfast or whatever), and then the B&G do some version of having guests pay a portion of the costs by charging them for their rooms, which basically means guests are paying at least a portion of the wedding venue fee. For example, if a B&B is the site for the wedding, but requires the B&G to rent out all the rooms for the weekend of the wedding as part of the site fee, and the B&G then "rent those rooms" to their guests. Something similar often happens with destination weddings; the "wedding is free" at the resort/site, if enough guest accommodations are booked at the resort. Sometimes WW users "brag" about what a deal their foreign all-inclusive wedding is going to be -- "free wedding and bridal suite," but it's because their guests are paying tons of money to the resort for accommodations and fees. There is often lots of push-back regarding those arrangements, as it's basically having guests fund the wedding....

From what you've described, I think you're fine. (However, if someone decides to stay elsewhere, even if you feel like they committed to stay at the Airbnb you arranged, I'd try to take that in stride.) Good luck!

I don't think it is rude especially if this is something you want and you need financial help so it fits in your budget. I think most bridal parties expect some cost along with agreeing to be a bridesmaid or groomsman. My girls are helping pay for the hotel room that we are sharing the night before the wedding. Asking them wasn't difficult because they aren't breaking the bank with the dresses so I feel a little more free to ask them to help with other things.

I don't think that's rude at all. It will save your bridal party money in the long run b/c they'd pay so much more than that for a hotel on their own.

Since you asked ahead of time to see if anyone was interested and able, it sounds fine

No i don't think so! my bridal party paid for their own without even questioning it. they actually made their own plans for accommodations.

perhaps you could offer the air bnb first? tell them youd like to all stay together and this is how much it would cost everyone.. then go from there.
