The panel room

You decide to head into the building and head straight to the main panel room to quickly take a glance at the agenda. The first panel of the day is for the TV series community and with your powers a quick scan tells you the cast are already gathered in the green room preparing to head on.

At ten there's a DC/CW panel with combined cast members from Flash, Arrow and Supergirl, before a Game of Thrones panel at eleven.

All those stars before lunch sounds like an irresistible buffet. Should you head into the green room now, or see what else is about and come back for a later panel?
