Tips for Entry and Music Den!

Hello! This is going to be my first ever KCON and I’m only going Day 3. I was hoping people have tips on how I can get into the Festival Grounds ASAP to get into Music Den to see Modyssey and Nexz.

Is the express ticket worth it? And how early can you purchase it? Do I need to use the queue for Music Den through Mnet? And do they clear the room out between acts or will I be able to stay for both (11:00 and 12:00).

Also for Mcountdown, if I have a seat number do I need to worry about getting in? How early do I need to line up?

Thanks for the help!!
