Of course M is right - I thought there was something about back-to-backs that I remembered....

From the RSSC web...all the more reason to book a second week, K!!

Q: If I become eligible for a higher benefit tier while I'm on board, when can I take advantage of the additional benefits?

A: Your new tier benefits take effect at the conclusion of your cruise and will apply for all future sailings with us. If you are on back-to-back sailings, your new tier will take effect at the beginning of the second voyage.
