I know that everyone does not agree, but it has been my experience that a 14 day cruise that is bookable as two 7 day segments will receive the Premier benefits, suite benefits, and Elite benefits (if applicable) as if it was two seven day cruises.
i suggest you log into your account on Princess.com, click on luggage tags/travel summary. Click on travel summary and scroll down to the bottom to see what is included with your booking. You can also print it.
Look at the $ value for the speciality restaurants. This does not include the first night free speciality for the suite. If you booked prior to December 1 it will show two 360 experiences.
