I was only there one night but they upgraded me to a ocean-front view, in a HUGE room. From the balcony could see the people on the jetty at 7 am watching the sun rise over Diamond Head. They even have a courtesy room to use if there's a time gap between your check-out (12 noon) and a late flight. Not cheap (particularly the $35/day parking) but you get what you pay for.
I have been staying at the Hawaii Prince for years...every trip to Honolulu. It has a great location, wonderful staff and easy in and out for all areas of Honolulu. I love the views of the harbor... I sleep like a rock when I am there because I have the option of AC or open air...
Great room with awesome view. Room Service is good. Very comfortable bed and room is very good with great amenities. Location to everything in Waikiki is close and in walking distance. Highly recommend this hotel if you don't want to rent a vehicle.
best hotel I've stayed in my life. watch luau show there, has on site parking. many diners and bars. pretty much everything you need to live and have fun and there. hard to leave. also pricy, but totally worth it. since you are on vacation in Hawaii, might as well go big and get the best experience.
