First of all, don't go to Princeville if you want the typical Hawaiian, hot, sunny experience. I think Princeville is the most beautiful place on the Islands, but it's been rainy and chilly every time I've been.
The St Regis is also not your typical Hawaiian hotel. It doesn't have that indoor/outdoor feel you'll find at other resorts. It is beautiful with amazing views, but it's definitely closed in, and the lobby areas are COLD!
Also, none (most?) of the rooms facing the water don't have balconies.
The best part is the service - it's amazing. The staff is so wonderful, accommodating, etc that they make me give this property an extra star. (Without the staff, it's a 3 star.)More
