Great, memorable hotels in Hawaii?

The Grand Hyatt.

My personal top picks are the St. Regis Princeville on the island of Kauai is number 1. The Royal Hawaiian in Waikiki on the island of Oahu. Turtle Bay Resort on Oahu’s north shore. As @papayalily said The Garnd Hyatt on Kauai is amazing. Also Kauai Marriott and the Marriott Maui Beach club.

I second the Royal Hawaiian. It’s really second to none

It’s been a while, but the waikiki sunset hotel was awesome on Oahu.

On the Kona side of the Big Island, I recommend the Mauna Kea Beach Resort and it’s sister property, the Hapuna Beach Prince Hotel.

The best hotels on Oahu are Halekulani and The Kahala
