Actually, many cruise lines changed the rules lately about these loyalty program qualifications, so even 3 or 4 night cruises don't necessary qualify or bump you up to the next tier upon taking x number of cruises. Not sure about HAL's current rules on this but the above changes applied to my preferred NCL program - so no repeat cruiser status for doing a 1 nighter. The perks had been cut back too until you reach the upper tiers, 12+ cruises or higher - yike, following the trend with the airlines industry & their programs. But, for what it's worth, cruising is still a bargain comparatively speaking, unpack once & then for the next 7 or 10 or 12 nights or what not, everything stayed in the closet - then, just repack once & disembark/head to the airport or drive home if sailing from home port.

And, surprising affordable on many lines .... as long as one keep tab on the bar charges, casino visits, bingo games and duty-free/off-shore "bargain" shopping & diamond specials onboard. (Edit: NEVER, NEVER bid and buy any onboard art auction items on longer cruises, it's a rip-off)
