Tricky question ... as we no longer "tour" Oahu. Our former employer had an office on Oahu and we visited frequently. Now'a'days, our trips to Oahu are to catch up with friends from that period of life. Thus, we generally stay at the Hilton Hawaiian Village (Waikiki) or with friends in Pearl or Kailua.
Frankly, for "touring" -- I think Waikiki is awesome. Mostly "central" except for the long drive around the island to the North Shore. We enjoy with "walkability" to dining, aquarium, churches, .... sight of Diamond Head ... and reasonable drive for Pearl Harbor, beginner snorkeling locations, Aloha Stadium Swap Meet, etc.
Just skimmed your "DVC Every 3rd year" thread. FWIW, we own/use
Worldmark the Club for most of our western states adventures, including HI. Very affordable ... lots of locations ... good quality ("nice Chevy" not BMW?) ... dependably clean ... highly functional timeshare. Works
really well for us!
Your other thread also touched on the idea of inflation. My comment on this: I'm really glad we purchased DVC when we did (2004). We are very much enjoying the "fruit" of that decision in this new phase of our lives (recently retired but not by our choice). We've been staying at Disney's Grand Cal in either 1BR or Studio units as often as I can snag reservations (using up all our points!!). Looking at the cash prices for similar stays is a shock. There is no way we could/would (now) book these same stays as cash reservations. We are
quite thankful for our long-held DVC points!
Best wishes on your research, deliberations, decisions, etc.
