I was just at the Cosmopolitan for a three-night stay, checking in on Monday, February 22, 2016 and checking out on Thursday morning. Here's a brief summary. Monday night: I was having trouble with my wired internet access. I called and asked for help. The first guy they sent up wasn't able to fix the problem (and broke the wooden frame of the mirror in the living room while trying). Two phone calls and a 90 minute wait later, the second guy they sent up did fix it. I asked to speak to a Guest Services manager to complain about the long wait. I was told I'd receive a phone call but never received a phone call. Tuesday night (and into early Wednesday morning): Internet troubles again. I called and they told me that there was some maintenance being done. I was not informed of this maintenance earlier. I asked to speak to a Guest Services manager, but no response for an hour. I called them back, but they hung up on me mid-conversation. (To be fair, I'll note that the Guest Services manager eventually did call me back.) The Front Desk manager assured me that another manager would follow up with me during the day Wednesday, but no one did. Wednesday night: I called Room Service to arrange for them to pick up some plates from a previous order I had made. An hour later, no one had shown up. I got sick of waiting so I put the dishes in the hallway. I heard them at my door another hour after that. (If I had kept waiting, it would've been a total of a two-hour wait.) Side Note: Whenever you ask to speak to a manager, they always try to talk you out of it. "What is this regarding?" "Is there anything I can do to fix it?" instead of "Sure, I'll go get the manager." I've since spoken to Brian Askins, the Senior Guest Services Manager at Cosmopolitan. He did offer me a two-night comped stay for my trouble, but I declined. (Money isn't the issue. Rather, I'm furious they ruined my vacation; money won't bring back my lost time.) He said he would follow up with an e-mail. I plan on showing him this thread if and when he does follow up.
