I was thinking "Much ado about nothing", but I take that back - and make a suggestion: Offer a menu of choices, for example: After (some # of) [cruises][segments][nights - my initial choice], guests can choose (A) or (B) or (C), where A, B and C are SSS benefits. Then, after (some additional #), you can have your choice of (D) or (E), but also still be able to choose from A, B or C, etc.

Coupled with this REWARDS STRUCTURE would be PRIVELEGES cruisers could become eligible for as they cruise more and achieve higher tiers, such as: FREE INTERNET SERVICE, free laundry*/dry cleaning, early notice of offers, the ability to make reservations for dining, excursions, etc. before departing, either to a separate, better staffed (unlikely to happen, right) phone center, or on-line.

It seems to me this method results in more happy cruisers, AND less competition for scarce resources-openings-etc., since (as my dear sainted Mother -G.R.H.S.- used to say: "Each to h][er][is] fancy, and me to my Nancy, said the miner as he kissed his mule !. (I'm being overly pol-cor here, but she always said 'his', since the miner was presumed male, and she was an English professor and teacher as well as a poet, or more properly, poetess.) Bottom line, more choices, less crowding, same basic cost to RSSC.

*NOTE WELL- RSSC should use care in messing with the laundries, as these facilities may well be a small but key part of the socialization structure on board the ships!
