Advice on Maui or Honolulu?

My fiance and I have decided for our honeymoon to go to Hawaii. We plan on staying at either Maui or Honolulu for 5 days then do the 7 night Hawaiian cruise so we can visit the other islands. The cruise ships leaves Honolulu. My question is whether we should just stay 5 days in Honolulu to relax and enjoy it or go to Maui for the 5 days and take the 20 minute flight over to Honolulu the day the ship leaves. The cruise will be docking in Maui for 2 days. I've heard that Honolulu is pretty much just like a city and very commericalized. is there anything fun to do there? Any recommended resorts?
