Check the program and decide which performance matters to you. If the organizer publishes set times, use them to plan your arrival. Allow for the queue and any ticket deadline. A late start can work for your evening if you know how you will get there and which part of the program you are likely to hear.
Tell friends roughly when you expect to leave and whether you plan to travel together. Keep your ticket, belongings and transport details accessible so an early departure is straightforward. If you become tired or stop enjoying the room, say so plainly. You can spend a shorter time at the event and still hear the music you came for.
Look up transport for your intended leaving time. A service available at arrival may finish before the event does. Find the pickup point or station entrance in advance, and leave enough phone battery to use your booking. An independent return option also lets friends stay longer when they want to.
