My girlfriend goes to EDM music festivals and clubs with her single (very promicuous) girl friend. Should I be worried?

So I've only been dating her for about 3 months and already she's gone to two huge electronic music festivals (booked before we got together) with her single friend who seems to meet guys at every event or time they go out. On one occasion her friend ditched her at a club in Europe to go back to a hotel with a guy she met that morning and went back to the hotel with him, leaving my girlfriend alone at the club. Not cool in my opinion and I said so, but she's not my friend (genuine concern for my girlfriend being alone at a club) Then last weekend she went to a festival in NYC and they got ridiculously drunk ion their first day there and at about 8pm that night I got a text saying "I left the festival" and then was unreachable by text or phone for several hours (i was very worried of course, and my mind wandered to places where she might not want to be reached at that time) but I called her at 3:30am and she finally picked up and said her friend had met up with a dude she had met on one of their previous trips and his "ginger troll friend" and she couldn't deal so she left by herself (very drunk) and went back to their hotel and crashed hard. Was probably about an hour journey back to her hotel but she didn't write me in that time (other than "I left the festival") whereas she was texting me the whole time her friend ditched her at the club on the previous trip. She said she was so drunk she just wanted to crash. I believed her. We talked about it when she got home and it seemed like a plausible scenario. She has another trip planned in a couple months with this same friend. I'm worried she could get super drunk and this time her friend will meet a guy who isn't a troll and is hot and fun. Am I being paranoid that she could drunk cheat (even though she says she's in love with me and would never do anything with another guy) or worse get ditched by her friend and get into trouble when she's wasted and alone. Both bad but one is way worse. What should I do?
