OK. I got the skinny on what happens if you can't pay by the deadline date. Basically the PVP ( or TA i guess) requests an extension for you. If you don't pay by the extension then you lose your booking and deposit. I am not sure how long you get an extension because, luckily for us the couple that couldn't pay originally DID find another way to fund the rest of the fare. So all is now good for our first cruise with friends on Freedom in Sept!
