Utterly Disappointing, will not return
Hilton Diamond member, one night stay, several issues that were brought to staff and management attention, but were not fully resolved during my stay:
 1.) It took at least 3 visits to my room by staff, 2 trips by me to the front desk, and 1 hour and 20 minutes to get working keys for my room (most of that time was in the hands of the front desk manager). Of the 19 hours I’m allowed in the room, that was a considerable slice. I had a pretty tight schedule for this visit, and this affected my trip significantly. 
 2.) Despite verifying my credit card at check-in, I was twice unable to charge to my room (at McClellan's bar in the lobby, then after speaking to front desk staff and again to the front desk manager, my parking). Both incidents were embarrassing, and the parking caused me to miss an earlier flight home. 
Hilton Honors customer service involved themselves when I tweeted friends that I was held up (room keys), and they only complicated matters. I checked out on Sunday, by Wednesday I had sent them a 4 page letter detailing my stay (insisting that nothing be comp'ed). 10 days later, I had to follow up again because I still had not received my eFolio. I was told everything was comp'ed, which told me HHonors Customer service had not read my email or my letter. Whey they corrected the bill, it only had the dining charges and not the parking, so I again sent an email to fix that. 
Compliments 
• The service, food, and drinks in McClellan’s were very good, and the atmosphere was nicely balanced (noise and aliveness from the people, but still able to have a conversation)
• That was the first time I had sent a text message to retrieve my car, and aside from the room charge issue, the process worked well
• The lobby and room décor are modern and tasteful, some of the nicest I’ve seen in a Hilton
• All of the staff (except the gentlemen who closed the Concierge Lounge door in my face) had great first-level customer service skills (polite, friendly, competent to do their job). 
Overall Observations
• All of the staff would benefit from additional training on handling guest problems. My expectations were not that things be fixed immediately, but I expect hotel staff could resolve guest problems without my supervision.
• This hotel is severely lacking in posted signage: the Banquet entrance would benefit from a sign that says “Guest Entrance” and points up the hill, the Concierge Lounge would benefit from a sign which posts the hours it is open, and service hours (e.g. continental breakfast 6am-10: 30am). The guest room doors would benefit from posted escape routes and checkout times. 
• Perhaps 11:00am on Sunday was a bad time, but the Concierge in this hotel did not strike me as amenity (I'd like to review breakfast, but housekeeping kicked me out before I could order roomservice, and the concierge lounge was wiped out by 11am). The hours were not posted at the door, in the guest directory, nor were they explained to me at check in. 
• The guest directory would benefit from a review. It had a lot of information in it, but nothing that I was looking for.
