It's simply misleading to think WAIKIKI or HONOLULU represents all of OAHU
Granted most of the major hotels & timeshares are located in Waikiki but that's because it's the major city at this destination.
Just like Lahaina or Wailea doesn’t represent all of Maui
Waikoloa doesn’t represent all of the Big Island
New York City doesn’t represent all of New York State
Los Angeles, San Diego and San Francisco doesn’t represent all of California
For me, Oahu represents the best of both worlds. It offers me all of the things I want in a vacation destination along with all of the beauty of Hawaii. Just like any other destination, if you leave the major cities you have a whole other world to explore and discover.
JMHO... each major city has a different feel/vibe (for example NYC, Las Vegas, Chicago, Denver, Los Angeles, San Diego, Seattle, San Juan, Paris, London, Rome, etc). With Waikiki I get the convenience of a major city in a very relaxing (aloha spirit) type of environment. Yes, there are crowds and traffic but that hasn't stopped me from visiting any other major city
Oahu offers a very enjoyable combination of a major city & tropical vacation destination which is the reason we visit Oahu so often
