Some problems but resolved by Mgmnt
I have been staying at this hotel for over 20 years and have witnessed its transitions in decor and management. I will say my issues with the property are not relative to condition of the property, either in public areas or within the room which I had on one of the Executive Level floors. The hotel continues to show well and generally does a good job in most aspects. 
The one issue with this hotel that is simply unforgivable is the poor shuttle service from the Airport. One would think being a hotel property and having over 1000 rooms, a sufficient service would be provided. The excuse I received from the line staff was the hotel does not operate the shuttle service and they have no impact on the quality and/or quantity of vehicles used. I arrived at a generally busy time in LAX and waited an extended period for the shuttle service to the point I called the hotel to ask the status. This is when I was informed of the information above and the person generally had no regard to my concerns and simply said the van was full and they only operate one which translates into it would be about 25 minutes until the van returns to terminal 5. Make note, if your airlines comes into Terminals 1,2 or 3, you will have a great chance of getting on without a problem. If you are in terminal 4, 5 or 6, your chances diminish greatly depending upon the time of day. By the way, the same can be said for the return trip from the hotel. We got to the lobby at 745am for the 8am shuttle trip and the line was through the entry door and we didn't make the van service because, the shuttle was full. Again, for a 1000+ room hotel, a shuttle that holds about 20 passengers is insufficient and inexcusable. This issue was never resolved by management.
I will not go into any additional details about what I experienced because I do not believe it was an anomaly and it would not be fair to besmirch the individual who I had issue with. Suffice to say, Management did intervene and made the appropriate decision in order to rectify the problem. 
In short, I believe all hotels in the LAX corridor are having similar issues with the van service and some kinks have to be worked out. The hotel itself certainly was more than acceptable and continues to maintain the Hilton image even throughout all of these years. Our rate was just over $200 I believe and that too was acceptable. 
We tried room service which was delicious and timely, as well as the breakfast in the main restaurant which was very good. On another note, during our stay they were putting in new carpet on guest room floors and doing some painting.
