My wife and I stayed here for 3 nights as part of a driving holiday around Southern California. Had stayed here many years ago at a convention - had some concerns having read earlier reviews. We booked into a Regency Club room in the Tower and the room was fine but not great. The food in the Club was poor and the service pretty much non-existant.
On the positive side the hotel is in a great location with great views over the marina, also its very quiet so guaranteed a good nights sleep.
We didn't eat in the restaurants as the menu was pretty bland and overpriced but plenty of good restaurants within a 10 minute drive
