As a Platinum SPG member, this was our first time at a St. Regis, and was one of our best experiences with the resort and its service. On our trip to Kauai, we decided to stay 2 nights at the Westin and 2 nights at the St. Regis in Princeville. Upon arriving to the hotel, we were pleasantly greeted at the valet and the front desk by Jessica (front desk supervisor). Our room was not ready as we had checked-in early, but after providing our cell phone number and walked around the resort area, Jessica called us within 20 minutes to let us know the room was ready.
We had booked the room with cash and points and I had applied 2 suite awards for an upgrade to a junior suite. They upgraded us even more to a junior suite with a terrace having a view of the Hanalei Bay. We were greeted by our butler Greg who immediately brought us coffee when requested. The room was wonderful, with a king size bed, living area space, and the bathroom exactly how they described it on the website. The bathroom had a expansive glass window electronically controlled for view or privacy with the switch of a button. The only negative thing with the terrace is that even though you have your own personal outdoor space with lounge chairs, you're sharing with other suites on the grass terrace, so anyone walking along the terrace can see inside your room. Therefore, we had to keep the glass window in privacy mode the entire time.
As platinum members, they offered continental breakfast, but we bought up to have the full breakfast. Sunday has brunch only, which cost a little more. The food isn't cheap at the St. Regis, and there isn't many restaurants around the Princeville area. Even with the buying up option, we ended up paying $100 for brunch and $50 for breakfast for 2 people, including tax and tips. The food was delicious, with brunch having a lot more variety of foods, including shrimp and crab legs. We never tried the restaurants for lunch or dinner, so we can not rate them.
The pool was quite nice and relaxing, and have a beautiful view of the bay.
Overall, we had a wonderful experience at the St Regis Princeville Resort. When comparing the Westin versus St Regis, the Westin is great if you want a kitchen, but for the views, the pool/beach, and the service, the St Regis is the way to go! We haven't seen all of Kauai, so we intend to come back again!
