We are totally biased but we love the Four Seasons O’ahu at Ko Olina. In my very honest opinion (and hey, that’s part of a travel professional’s job) - it is the only real resort on the island of O’ahu.
The Four Seasons O‘ahu is a getaway within a getaway, and I am immediately relaxed upon entering the porte cochere.
I should also note (for legal reasons), that I have not received anything of value from the Four Seasons Oa’hu in exchange for this post. We paid the kama‘aina rate like any other Hawai‘i residents (call for availability - they don’t have unlimited kama‘aina rooms available). These are my honest opinions and firsthand observations.
