It is as long as there are well established rules, everybody is clear about the interactions they like and everybody knows the rules and how open are the others to different interactions.

In my personal experience, the biggest problem is always a dude that wants to fuck/grope every person in the group but gets mad if someone barely touches his partner… Or worse, single dudes that feel entitled to every other person in the group and get angry if you don’t “get out of the way” when they pick a “target”

Also, get ready lots and lots of towels and water bottles
