AITA for refusing to babysit all of my nieces and nephews at a wedding

My sister is getting married. Its a big event for our family, being that my sister is the last of our brood to get hitched. My parents are quite thrilled, so they are sparing no expense. The reception is going to be at a swanky country club in the mountains with a lake...very pretty and very expensive. Over 150 guests are attending, and they have spared no expense on flowers, food, and drinks, not to mention the band. And oh yes, open bar. <br><br>My sister has 7 siblings. All of us have kids. There are 22 in all, from age 1 to 13. 7 of my nieces and nephews are under age 5. Traveling to the venue is also a trek. Its a 6 hour drive, or a 2 hour flight. So, I, along with pretty much all of my siblings, have to shell out some big money to travel to the wedding. <br><br>Here is my problem. My parents and several of my siblings think that all of us should bring our kids. My parents have insisted that all 22 of the grandkids come. First of all, this is going to make the wedding CRAZY. Secondly, it is incredibly expensive to bring all of them. Third, while the reception is a complete blast for adults who want to drink and dance, there is not really anything for kids to do there and there is a six hour drive home. And they want all of us to drag all of our kids along for a night that is basically geared towards the adults. <br><br>I am the only one who has said no. My sister is very understanding about it, being that she does not really want kids running around the reception. However, my parents are pissed off that my kids are not coming and so are several of my siblings. They tried to guilt me into bringing them by pointing out how expensive it is to leave my kids at home. <br><br>AITA for not bringing my kids?<br><br>&#x200B;<br><br>Edit: I did not say that I was not bringing my kids because they are a burden. I was not bringing them because I did not think that they would enjoy the event, it was a long way to travel for a night that was going to be hard for kids, and I wanted to really enjoy the wedding without worrying about them. I did not want to disturb other guests either. This was not a child centered event, it was for adults.<br><br>And no, I am not hiring a babysitter for my parents' home. I am leaving my kids with their father. <br><br>And no, I am not refusing to come because of the kids. I was refusing to bring the kids.
