Probably getting a good deal on a luxury lines would be the key to getting those of us curious, yet trying to keep within our budgets to the ship. All inclusive would be nice but if there is a nice on board credit like some lines have then we wouldn't need the all inclusive.
Probably a 7-10 day cruise would be good for most. I guess the idea would be for those of us, who would consider such a cruise, to be able to afford it. If it would be as good as I expect it would be then I probably wouldn't go back to the main lines and the luxury lines would have a customer for life.
