I'll go near the NPC and keep looking for a squad then!
just take the quest, and it'll teleport in.. and inside.. there is a waiting area where there will be 20+ people (at the start of the event) and you will find plenty of squads inside.. but the best way to get chrono page is card bosses... will be much faster.
Okay, so, I'll tele in and look for squads. And, yes, I'll try card bosses too, but, I've heard that it gets really long and boring.
