Best friend not coming to bachelorette party

Seeking a new perspective or wondering if I’m the asshole for expecting too much?
I’ve been planning my wedding and parties leading up to for about a year now. And I have 2 best friends who said they wouldn’t miss any of the parties or the wedding for any reason!!On top of bachelorette party the 21st and wedding/ and reception on the 25th I am also throwing a “welcome party” on the 23rd that I told them they did not need to attend like if they can’t get off work for three things I totally get that!! But we all agreed bachelorette party and wedding are most important obviously. Now my bachelorette party is 3 days away and she says she can’t make it for financial reasons. Mind you I got a limo and planned this all out and it wasn’t easy and it wasn’t super cheap. I also am providing LOTS of booze the only thing she needs to pay for is her OWN food at the restaurant. And IF she wants to buy drinks at the bars WHICH AGAIN I have lots of booze she she’s probably not going to need to do that… like
I guess I’m posting to vent but to also seek guidance on how to respond gracefully because my first instinct is to just be short and snippy and say “oh. Ok.”But I also want to point out that she literally doesn’t need to pay for anything except food. Should I push a little and say that or should I just get over it and don’t be a brat. :/ lolAlso a little side note is last year I planed our trip to Miami for their birthdays (I have 2 best friends)(both their birthdays are in July) and I planned it all by myself. And the two girls and myself just split the cost equally.) My friends are a bit younger than me they both just turned 22 this July and I am 28. So I kind of just fit into that “mom friend” roll but idk. And I will also add that I had not been the greatest this year for their birthday I missed her birthday dinner because I couldn’t get the time off last minute she told me 1.5 weeks before the dinner and I’m a baker at Panera so there is no one to just cover me if I miss work without notice. And she knows this. But we planned a night out to celebrate both of them to make up for it yesterday and she didn’t even come to that. Because she decided she didn’t wanna go to a club and instead go bowling which NONE of the other people who were attending wanted to go bowling instead of to a club. I was willing to bend but we already made the plans and no one else was willing to bend.
