Theft disaster
I have never before now stayed at a hotel that markets itself as more than 1 star and permits an unconcern with security or lack of professionalism in dealing with the aftermath that I saw at the Adagio.
I left my luggage in their safe storage room on arrival, as my room wasn't ready yet - except that when I came back in the evening, I was handed only one of my two pieces of luggage, as apparently they "couldn't find" the other one. After being pushed around while no one below the manager (who wasn't around, as this was the weekend) was able to say anything conclusive I finally cornered the manager almost 2 days later. At this point I was told that they're very sorry, there was a security breach as a thief was able to walk into the hotel, walk into the safe storage room (it was, it appears, a cupboard that stored, along with guests' luggage, a large amount of renovation-related equipment and had workmen walking in and out all day) and walk out again with several pieces of luggage including mine! They weren't able to provide any coherent explanation for why they used such a patently insecure location as a "safe storage" room or why it took them almost 2 days to come to this conclusion, but at least promised the hotel's insurance would cover replacement of the belongings. Unfortunately after almost 3 months of exchange of emails, phone calls and voicemails, nothing of the sort has materialised, everyone is backpedalling to "there are no obligations under CA law" and the general manager isn't even returning my phone calls. 
Needless to say I will be going out of my way to avoid any hotel managed by the group, and strongly recommend you do so also. As a result of their utter incompetence I lost over $5,000 in belongings, and have very little faith at this stage that I'll get any compensation.
