Nice Room - Valets Ego Bigger than Hotel - Check In Delays
I had stayed at this property at least 5 times since 2006. I recall it being listed as a 3.5 star a few years back and now suddenly it is listed as a 4-star. I think 3.0 - 3.5 is more realistic for the property. I see no evidence of improvement that would warrant an increase in the rating.
We were given a handicap accessibility room although not handicapped. The room was fine, carpet cleans, and bed comfortable. For the pricepoint, the room was perfectly acceptable.
A few areas where the property falls short relate to staff training and attitude. You will find dramatic differences between West Hollywood or Beverly Hills property staff and the LAX Hilton staff; expressed primarily in a latent dispect for the customer base which bleeds through artificial smiles and QC/CS expressions.
Some points to note:
1. The prominent security relate both to the geography and the customer base serviced and you will find similar security in nearby food establishments.
2. The check-in queues were SUBSTANTIAL and there are no automated check-in alternatives at the property and thus you should prepare youreself to stand for some times amidst the noisy crowd from the most recent tour group laying over.
3. The valet process is irritating. They have an automatic ticket reader for retrieval and are quick to direct the customer to try to use the machine vs. helping the customer to do so. My guests from the film industry were shocked by the attitude of the valets and remarked aloud "this would never happen in Beverly Hills". Once again, HILTON and CUSTOMER should be advised that they EXIST and TRAVEL for the EXCLUSIVE financial benefit of the Valets who are not in a subserviant facilitating role; but rather a leadership role and you the customer should benefit from their learned discourse and warm glow of their presence and genuflect in their presence.
4. The parking validation. You have a few drinks. The bartenders have their contention with the wait staff over transfers trying to defend their tips. You give them 20% to your room and this not being cash-- you get an angry look. They then run-off with your bill with no invoice. The valet tells you that you need a validation. So you go back to the bar. Your bartender is not there. You have no ticket. No one knows who you were though there for 2 hours just minutes prior. You ask another staffer who shrugs his shoulders. You ask another bartender too busy to help; afterall your tips have already been given. You spot your old bartender; but he's too busy also. It seems a 15 dollar or 20% tip is just not sufficient for any basic form of Customer Service. Once again; the SILLY CUSTOMER forgets to genuflect while in the presence of the staff. 
Make sure you do the room check-out -- because the check-out queues can be quite lengthy as well-- and you wouldn't want to miss your flight on account of it. Also call the valet for your vehicle at least 30 minutes ahead as well just in case of that queue. 
And always remember...... you are ONLY the customer.....
