I found this on the TD Garden website last night regarding GA policy for the stay in Boston
Important information for GA/Floor Ticket Holders:
Security will distribute numbered wristbands beginning at 8AM each show day in the foyer of Stair 4, located past the TD Garden Box Office on the West side of North Station. GA/Floor Ticket Holders will be allowed to line back up at Stair 4 at 5PM. GA Doors will then open at 6PM.
Please be advised that all GA/Floor tickets are paperless for this event. The original ticket purchaser must attend the event with the credit card used to purchase AND
