Not the whole month on Oahu
I saw Honobob's comments and I certainly understand the problems he is relating about getting the whole crew up and down and around.
Nevertheless, Hawaii is so much more than Oahu, and with the luxury of an entire month, you could do two islands and still be relaxed. It sounds like your kids are fairly well-traveled. I have always found kids liked the least predictable and often, simplest, things. I still think The Big Island has so much to offer. Where else will they get to visit an active volcano? And history at The Place of Refuge is very impressive, and the snorkeling there is great.
Again, I would go for 3 islands, but 2 would be better than an entire month on Oahu. You will not be able to use Superferry for daytrips to other islands. The schedule and pricing just doesn't work that way.
