Dumb question about port parking in Miami...prepay or post pay?

Hi! Did a search but couldn't find an answer...we haven't parked at the port in a long time and usually use off site, but will be on Carnival Horizon from Miami, and decided to park on site after reading opinions from other CCers.

Dumb question: with Carnival, do you pay upon arrival, or after the cruise when you pick up your car? And do they take cash only or do they also accept debit/credit cards?

Thank you!

You pay when you exit the garage at the end of the cruise. Yes, they take credit cards.
