Spent 2 nights at Terranea recently while attending a business meeting. This is a top shelf resort run by Destination Hotels that is a perfect location outside of the bustle of LA. It is built on the former Marine Land and is situated on the cliffs above the Pacific. The views are fantastic, the rooms are well appointed and the service is impeccable. I used the gym every morning and it has everything you need to keep your workout routine in tact. The only complaint I had, and it is a small one, is that the it does not open until 6 AM. It is not a big issue for those who are vacationing and relaxing but is kind of late for those who are unlucky enough to be attending business meetings.
I will be looking to come back and bring my wife for a long weekend. I would not bring the kids as it is a little high end for them. There were kids there but they seemed somewhat out of place.
My room was in the main hotel but there are casitas available as well. Staying in a casita would add to the ambiance and provide a nice retreat to escape to.
Overall a very, very nice place1
