This hotel is by no means perfect, but I have yet to find one that is. There are a few minor flaws, but overall it is too beautiful to pass up.
The view is AMAZING. The hotel is perched on a cliff in Hanalei Bay (part on the bay, part on the ocean, but the beach is on the bay... and the bay is a calmer setting for snorkeling, paddle boarding, kayaking, etc.) The mountains are extremely close to the hotel, leaving you with a view that will take your breath away. I traveled all over the island during my stay, and the north shore is far superior to the south in terms of topography. The St. Regis has the best location on the north shore.
The service is overall very good. There were a few areas that I felt could be improved upon (pool food servers were overwhelmed because the hotel was busy, so it took awhile at times for them to ask if you needed anything; also the beach/towel service were not the friendliest at times). Valet was quick and very friendly- always ready to provide water, towels, etc. The concierge service was friendly and helpful, though busy. Check-in and check-out was gracious and efficient. Spa service was friendly and punctual. Housekeeping very good, friendly, and provided twice per day. I called the front desk from my room to ask if the sundries shop carried band-aids (I cut my foot), and they immediately sent up a first aid kit for me.
Rooms/Lobby- the lobby is gorgeous. Beautiful bar, beautiful lobby, brand new furnishings, gorgeous views of the mountains and ocean. The room I had was an ocean view. It was clean and a good size. The bed was a king and very comfortable. I have read reviews that the rooms are dated, and I can't decide if that's true, or if the hotel is just staying true to the theme throughout the island- which is dark green and natural wood. The bathroom is dark green marble and the wood in the room is a medium stain. It does appear a bit dated (as opposed to the lobby which looks very modern and fresh), but this tends to be the color theme in this part of the island. Many of the local buildings and restaurants around the north shore are painted dark green- maybe to blend in with the lush surroundings? The bathroom fixtures were new. I didn't like the step up into the tub, and tripped once, and the tub has a dated rubber stopper which could be updated. But overall the room was very nice. I had no problem with the air conditioning- it was a digital thermostat that we could adjust, and our room was always cool and comfortable. The front exterior of the hotel is beautiful and modern, but the rear exterior facing the beach looks slightly dated- it could be updated. I felt the towels in the room were not as plush as you would expect at a hotel like this- they could be replaced.
The spa was beautiful and elegant- very friendly and efficient, and very expensive (as most resort spas are). Showers, changing rooms, and bathrooms here all very luxurious and new.
The food was very good but very expensive (but you tend to expect this at a resort like this). Pool drinks and food were very good. Makana Terrace for dinner has a gorgeous view- my food was very good but others I had dinner with said theirs was just fair. Maybe it depends on what you order. I had the lobster/corn/chorizo bisque, the macadamia crusted mahi mahi, and the creme brulee', which were all excellent.
The weather was perfect. I had heard that it rains a lot on the north shore so I was worried, but when there are clouds, they pass within minutes, and when there is a shower, it lasts for about 5 minutes and moves on, followed by sunshine, rainbows, and waterfalls. I think most of the rain comes at night. I counted 5 rainbows the week I visited.
As I said earlier, there are a some minor areas which could be improved upon, but overall there are too many wonderful things about the hotel to give it anything less than 5 stars. The good far outweighs the not-quite-good.
Did I mention the view? Unbelievable.
