We stayed at the Westin Moana Surfrider in 2019 prior to Ko Olina (5 nights on points); DH is lifetime titanium (whew he got in just before they stopped granting anything above lifetime platinum). We got full breakfast buffet for the 2 of us ($40/person value, and it was a fabulous spread) plus club lounge access and the lounge is now where a restaurant used to be off the lobby (continental breakfast, soft drinks all day, chips and snacks, evening salads, soup, heavy appetizers with free beer and wine). We had stayed there many times over the years, but but it had been quite a while. The perks there were awesome. It was a bit noisy, as we were upgraded to an oceanview room overlooking Duke’s.
If you considered this property, I’d call directly and ask regarding your kids‘ ages and whether they are free in the lounge as well, or if they can get the buffet included or reduced cost. If they can use the lounge, the breakfast there is honestly ample.
For Waikiki, we always used to stay at the Moana; it’s my DH’s favorite and we used to staycation there as well when we lived on the Windward side. Yes, the Royal Hawaiian is right there too, but the Moana is a special place to us. We used to drive at least one Sunday a month to have cocktails and watch hula, got to know the musicians there too.
