I would be shocked at 10 as well....the season would be over before all the payments were made. If you decided not to pay, it's not like they can cancel your remaining tickets. Of course, they can and as history has shown, take you to court.

Looks like the Marlins took a page out of Snyder's book (over promise, under deliver, cut back, & sue):

Love this line from a (former) Marlins STH:
“It’s just the principle,” he says. “If they would have provided what they said they’d provide, I’d still be a season ticket holder today.”
