My CS seats say I should set the price at 250 -- Does this mean that is what I should build next time I expand arena?
You desperately need luxury boxes and really, really need more courtside seats. In this case, "next time I expand arena" should mean "next time I have any cash at all". Doubly so those since they're actually selling out despite your error in pricing the seats - more bleachers and lower tier will eventually be needed but not until you're able to have your prices fixed.
