It is SOOOOOO fun!! Colin was a non-believer but always wished he had one by the end of the show hehe

*merch outside is what I meant lol

Sometimes they have merch inside of you gotta try and get in early once doors open. I'm usually a 'go during a song I don't like' person and a lot of times things are sold out so yea!!

Also if you want to get a light stick online they almost ALWAYS sell out at merch booth

Sometimes ppl will have dance challenges outside the venue or give out freebies, but generally you can just treat it like a normal concert and arrive whenev. Merch does sell out if that matters for you. If you want to go crazy you can learn the fan chants for your fave songs to yell
