I was in Oahu for 8 days! Spent some time in Ko'olina and North Shore, but mostly in Waikiki as the wife had never been there. We usually go to Kauai so it was a HUGE change for us. I have not been to Waikiki for 20+ yrs and it has CHANGED!!! The shopping was like being in Beverly Hills, or 5th Ave.
It was a decent trip, could've been better if I didn't have my obese in-laws with me . . . they can't do ANYTHING. But you gotta pay your family dues

We did have 3 days without them, so not a total loss
