@Ciara18 I'm not sure that's the right answer. The wedding wasn't the problem; the guest's entitlement and your discomfort with correcting her are more the problem. Please search the CC for some discussions on how hosts handle parties, do or don't allow additional visitors, how to charge for additional visitors. While you're there also do a search for how to write a poor review and then also do a search for how do I ask my guest for additional funds. Definitely write a dreadful review and then decide if you have enough evidence to ask for $.
(my listing sits right next to a town that bills itself as the Wedding Capital of Texas, I've hosted a wedding, I've hosted bachelor/bachelorette groups. It can be done well & the bride should have paid for the way she overused your home. A look at my House Rules list may give you some ideas. But also practice the phrase, "No we won't be able to do that" and then also, "Yes, of course, that sounds lovely, I'll send you the change order fee right away.")
And as an FYI, ABB Host Guarantee (a total fabrication but it sounds serious) only covers liability for the guests recorded in your reservation -- this is something many of us use to to either restrict or charge for extra guests.
