To Report or Not to Report

Long story short we had a work trip and the AM got way too drunk, came back to the shared hotel room with a male friend (I am a woman) at 4 AM, they kept me up till past 8 AM, then the entire morning, event, and car ride back she was vomiting.

I’m not trying to be an asshole and I’d like to be cool with my coworkers but maybe not that cool. She’s asking me to pay her back for drinks she offered now and I’m just feeling irritated. I don’t want to be drama or stir shit up and I do like her but I just feel like this is not ok. What do I do?
