So sad to hear about the Bel Air. It was my favorite. I loved the location, just far enough away to feel really relaxed and private, but close enough to get around albeit by car. My other favorite is the Peninsula. I have had wonderful service there always. They always upgrade my room, and I love the 24 hour check-in/check-out policy, and it is nice to be welcomed back woth ypur monogrammed pillow cases. When the long time GM left for the Montage I was worried, but the service is still top notch in my experiences. Negative is the pool is quite small compared to BHH and the area around it can get crowded (it is on the rooftop). But many times when I am there I am not looking to use the pool except for an early morning swim.
I have never been wild about the BHH, but do like the large pool, and some of the bungalows are great. Depends on what you are looking for!
