<human>: Condense the text into a few key points

So, I've been made co-MOH by my bride, and the first MOH put me in charge of planning the bachelorette entirely on my own. Okay, I can deal with that. 

Then she said she wouldn't be able to come, and made it sound like the reason is she's only 20 and wouldn't be able to get into the clubs. (Not true, BTW, I found both a dance club and a strip club that are 18+). The bride *really* wanted her sister there, so I did the research and found a way to make it work. 

Now that I'm working on the invites, she suddenly says she'll be out of town. The entire weekend. For something she does every year but "can't reschedule". Its vacationing with her boyfriend's family. 

...okay, *fine*, I think she's being selfish, but whatever, not my family. Unfortunately, two other bridesmaids are also saying they won't be able to go, one 'might' be camping and the other can't afford the gas to drive an hour to the town where the party is.

SO, question. Is it fair to ask these three absentees to still chip in to make sure the bride's costs are 100% covered? I'm not talking a lot of money, maybe $10-$15 each, the same as I'm asking the other girls to contribute. The bride wants dinner at Applebee's, dancing/drinking, then a visit to a strip club. I figure, with 6 bridesmaids and two other party members, we should be able to fully cover her expenses if we all chip in just a bit.

 They could just mail it to me ahead of time so that the money'd be available, and I could say stuff like " And THIS drink is from your friend BlahBlah, who couldn't make it tonight!"

Yknow, like including them there even though they aren't there, to help the bride feel better about her missing friends\selfish sister?
<bot>: Three bridal party members saying they can't/won't attend bachelorette, is it okay to ask them to chip in to cover the bride's food and drinks, like the rest of the party is?
