I believe I saw discount parking before I purchased my tickets and neglected to book it. Am I still able to secure parking at a discounted price

Look for parking sites like ICON Parking you can reserve parking spaces a few months in advance.

I'm not sure but you can book online before you go

Sorry, don't know. Parking is so expensive in NYC that we usually park at Secaucus, NJ and take the train to the city, making it an adventure for the family.

You should be able to, Check Groupon as well

Sorry. I do not know. I stayed at an hotel very closed to the theater.
