I was trying to figure out how it was done in Hawaii but noticed this:
Prince Preferred. It's tiered and you can earn status, but how is anyone suppose to hit that many nights with only 3 leisure properties in this part of the world?
Apparently the 3 Prince properties in the islands have their own rewards now, but if you look at their Japanese pages, they still credit regular Seibu Prince Club points (and bonus points), and have Seibu credit card (Saison) offers
