AITAH for cancelling a vacation with our family?

Hello! I am in a tough spot and I need advice….. I (30f) and my daughter (10) have been asked to be part of a wedding for a friend, a destination wedding. The trip ended up being pricey, and not something I could really afford. Our whole family is invited, cousins, aunts, uncles, the whole gang. since it was so expensive I decided that only me and my daughter would go because we have been asked to be bridesmaids. My husband (32m) and toddler are staying behind. My husband from the beginning has been against this trip because we cannot afford it and are trying to get ourselves out of debt. And of course, this trip has sent us into more debt. I have already paid for the resort, still need to buy flights which is going to cost just as much as the resort stay. We are approaching the final few months before we leave and before I’m not able to cancel at all…. I want to cancel the whole trip, use the money we get back to pay off some debt and fix my husbands car that has broken down this week so now he is paying $60 a day to uber to and from work. I know that I ATAH for trying to make this work when I should have been prioritizing debt payoff and having any kind of savings. But now I feel like an extra AH because I don’t know how to tell my daughter that we really need to cancel this trip. Her whole family is going, and her best friend (cousin) is going so I know she is going to feel like this isn’t fair and she is missing out on a special day with her family. What would you do? Still go, or cancel? And how do I break the news to my daughter if we end up cancelling?
