Although I am a Gold Ambassador member and my wife told the front desk staff it was my birthday on the day when we checked in, there was nothing provided such as a complimentary upgrade to Club
Level, free breakfast, reduced rate on room or parking or any type of amenity. It was sort of a "so what" reaction. I have stayed at this hotel many times before while on business, but that was of no consequence.
That said, the hotel is nice and in a great location (across the street from the ocean) with several good restaurants within walking distance. It's also close (20-minute drive) to LAX. [Less]
