Powerpass Card???

[seamare]

I was reading on the cruise critic information board and saw they were reviewing Hawaii and mentioned this card. We will be in Oahu for 3 days prior to our cruise and this looks like a good deal. Has anyone used this card or any others while on the island??

Along the same lines has anyone used the Hawaii Entertainment book (of coupons)? Is it worth getting? I heard it has 2 for 1 for the polynesian cultural center? Are the food coupons any good?
