Hi everyone, i'm in a bit of a dilemma and I really could do with some advice/opinions please.
Basically, when we were all beginning to look at flights late last year, DFs Best Man informed us that they were planning on inviting his mom and his wife's mom to join them on the holiday (we are all going for three weeks). They explained that their mom's (who we don't know) would go out for the day together whilst everyone was at our wedding. This was totally fine with us, it's their holiday too, so great, everything's fine.

However, when we came to book our flights in January, Best Man's mom decided she wasn't coming after all so it would just be his wifes mom joining them and she would stay at the villa for the day whilst everyone was at the wedding. Now, as you can imagine, we felt really bad for BMs wife's mom being all alone so we said, even though we don't know her, she was welcome to join us at the wedding. So we all booked our flights and that was that.....
Now, the other day DF comes home and tells me BMs mom has changed her mind and IS now coming to Florida with them..... I'm sure you can guess what comes next...."Can she come to the wedding too?" We've really felt like we're between a rock and a hard place, one mom is now coming to the wedding so we can hardly leave the other one out. The biggest gripe I have is the fact that I don't know either of these people, they could literally walk into the room now and I wouldn't know who they are. It kind of feels like we've been backed into a corner. Uggghh, I really don't want to sound like i'm being awful but, as I explained earlier, when BM originally told us that the two moms were joining them on holiday, they said they completely understood that we didn't know them and that there was no expectation that they would be invitied to the wedding. I just feel a bit upset that I have friends and family that won't be at the wedding, yet I now have two strangers coming. I think the fact that it just feels like it's all been assumed that it's ok has upset me too. We decided on a wedding abroad to avoid all of this drama and it's happened anyway.

I'm sorry to vent, I really don't want to sound awful. I can't leave her out, that would make me feel really bad, but I can't help but feel upset about this. Am I wrong to feel a little bit upset about it all?
Thanks for reading and letting me get this off my chest xxx
