Sure you can. It's up to you at any given time to go to the service desk and ask to pay what's on your account at that time, in cash.
That includes late on the last night if you want to close it out with cash.
You could even deal '' cash'' right from the start, at checkin, and pay $$$ on the account. However, that takes the flexibility of being able to '' sign on the go''.
