You can use ANY AMX card to pay a cruise fare and as long as you have an AMX Platinum card the AMX Platinum benefits are good. No Visa, Master Card etc can be used at all of course.
I would check and see if this is applicable to the insurance as well. If one benefit transfers the others may as well.
