Waikiki will probably be a one-off for us. An enjoyable experience and a beautiful beach, but the crowds in the water and on the sand reflect this. A fascinating people watching activity and great to be swimming in warm water again, but not first choice beach experience.
Interesting side note of Waikiki is the noise - endless construction beginning early in the morning and going into the night, and inescapable. You need to be a good sleeper or have some great pills with you! One friend told us she sold her apartment and moved out of Waikiki area because of the construction noise.
