To plan is to spoil yourself. For some, anticipation is just as important as the moment itself. Which party are you going to and with whom? What are you wearing? How do you get there? You can also think about whether you want to use alcohol or other drugs. And check with your friends what they are up to. Then you know what to do if something goes wrong.
Be kind to yourself and the people around you. If everyone pays attention to each other, everyone will have a good time. Do you see someone not feeling okay? Wait for a while until someone from the crew or the emergency room is there. If you agree on a meeting point at the party, you can find each other if your phone no longer works.
Better safe than sorry. Celebrate safe!
