Didn't your PCC email you the new invoice? I just called for my cruise yesterday and before I was off the phone she had sent my new invoice. Which details where the $ are.

I was told I’d have to wait, just like @prov2727, evidently. I don’t think I’ll get a new invoice, but a letter like @davencl because I’m past final payment.
