I just did an inventory search on Jan 08 on Grand. You out of luck for Jan 12th. They're sold out of balconies. On the 19th the Cat BD guar is available at $999. pp + tax.
On the 26th the Cat BC has one cabin on Aloha left and the option of a Guar, so you can choose. The pice is currently (as I type, but it could change) $1089. pp + tax.
BTW, there is an agency out there with some an onboard credit promotion with these cabins. The rates however would be the same through Princess direct or an agency. If you call Princess and mention the OBC, I'm betting they'll direct you to the right source to also get the OBC. They're very good about it if asked.
