I have been to LOS a couple of times with my airline and my view is that each place is as safe, or dangerous, as you make it.
We stayed in the hotel (only a short trip) and actually had a great time. The hotel was nice and the staff friendly.
For the person that posted about PHC, I am guessing from what you said that you are working for Virgin Atlantic. I think you will find that the reason the money is paid into our salaries is not danger money - it is to compensate for the fact that we are unable to leave our rooms etc and that it is a minimum rest trip. It is NOT classed as danger money by any official within VS.
