For Oahu I would recommend the Hilton Hawaiian Village, it is a great resort on Wakiki beach and a great family style resort. It's pricey if you can't find a deal but worth the money.
On Maui, they are all pricey. I stayed at the Westin in Ka'anapoli (sp?) this past Feb and loved every minute. Great resort and you can see the whales breaching all day long from the beach or pool. You may want to avoid a room facing the pool/waterfall/lobby area as the birds were very loud in the morning (early morning!). that said I really enjoyed the service and there are lots of shops and restaurants around the area.
If you are a SCUBA diver, I can personally recommend Maui Pro Diver, they were fantastic!
Have fun!
There is a book series for each island that has great tips/reviews and sites that most tourists miss. I really suggest getting the books for each island you plan on going to!
