so basically, my friends and I (we've been friends since high school) planned a trip to Miami together. We booked all the flights, hotels, and also got a rental car as a package from Expedia. There is 5 of us and this ended up being about 900-1000 per person (this includes activities we booked in advance) on the day of the flight, we all arrived at the airport, and we were going through the TSA when one of friends, let's call her Sarah, forgotten to wake up and missed her flight. We planned to get meet at the airport and we spammed called her phone but still no answer.

Sarah missed her flight and couldn't be able to attend the trip. Sarah got mad because since she thought that she wasn't using the hotel or taking up space in the rental cars she should be compensated some of the money back because she wasn't able to attend (not the whole amount but it would be around half) One of my friends said we should just do it and keep the peace, but I don't think we should have to, it's not my fault that she forgot to wake up and if we split it would cost me easily $200 alone, I can afford it, but it just seems unnecessary for me to make up for her mistake
I'm not sure what to do because I don't want our friend group to break up, but I also don't want to pay her $200 when I live alone and pay my own bills.
