Not deserving of the Double Tree name
I've stayed at many Double Tree hotels and enjoy them very much. I am usually in a hotel at least 50 nights a year so I understand what to expect. Check in was fairly easy here but no personalization whatsoever, even though I was a Gold member. In fact, the employee didn't even make eye contact with me and kind of just threw my cookie on the counter. 
I got to my room and realized it was decorated for the 1976 time period. It was extremely outdated and worn. My comforter had large rips and holes in it and the carpet had heavy wear marks everywhere. 
I can look past all of that but, at around 6pm when I was talking on my cellphone to my wife and was wearing only my underwear and undershirt, someone simply walked right into my room with their own key card. I came around the corner to find a security guard who did not apologize for being in the middle of my room without knocking but instead asked me if anyone left a pair of swimming trunks in my room. What? Needless to say I wasn't happy. 
Finish my night's stay with an unusual check out process. I am used to the ability to leave my keys in my room and have a receipt under my door. No suck luck here. I had to traverse the massive lobby and check out manually. No big deal except they checked out the wrong guest and gave me their $1,200 receipt for a one night stay. No apologies or anything, just another 5 minute wait while they checked me out. 
I honestly have nothing good to say about this hotel except for its convenient location.
Regardless, I will certainly not be staying here again.
