I lived in Hawaii for 2 1/2 years, depending on budget and what all you want to do...... Oahu is amazing, Disney just opened an amazing resort and if you stay in the less populated areas (Hawaii Kai, Kailua, Kaneohe, Ewa Beach) its relaxing And peaceful And yet if you want to visit tourist stuff its a quick drive away. If all you want is to sit on a beach, have a few drinks and relax, honestly I would either go to Kauai or Lanai. Smaller islands but not developed, very relaxing. And it is all gorgeous....... Wherever you go, you will LOVE IT!! :) let me know if you have any specific questions, I can help if I know the answer! ;)
