We stayed at the Ritz Carlton in Half Moon Bay for two nights as part of our Highway 1 trip. We loved the place! The location is spectacular, the cliffs are fantastic, the view to the ocean breathtaking, the rooms are quite small but beautifully decorated and equipped with all the amenities that you expect from a Ritz Carlton. We stayed in a few RCs before but this is for sure one of the bst we have seen so far. The interior, the bars and restaurants are very warm and cozy. The food is great and the staff is very friendly.
We are not Golfers, but I assume that this must be a paradise for Golfers. However, there are a few other nice things to do around the hotel: nice walks above the cliffs, good jogging trails and don't miss a visit to hthe village. The Ritz Carlton offers a free shuttle to main street HMB.
Downsides? Not that many, maybe that the heated pool which is located about 5 minutes walking distance from the hotel is not rally up to speed anymore. It looks a bit old. The fitness room next to the pool is also very old, so you should use the one that is located in the main hotel building. The Ritz also offers free bikes, however, unfortunately not for kids.
