I just got back from a weekend in Vegas. I stayed at the Cosmopolitan for the first time because they sent me a two-night comp. I can tell you I will never stay there again. As soon as I walk into my room on the 38th floor, I can hear the thudding music from the pool party. Distinctly. Loud. I immediately sit on the bed and call the front desk and ask for a room change. They tell me there are no other rooms, but the music should stop at Sundown. I ask specifically if this is going to be a problem at night and they say no. My friends show up in town and I am up until 4am, so I miss any issues. Unfortunately, I am also unable to take a nap the next day because of the next pool party. So I fight through it until 11pm and want to go to sleep. I get to my room and they have lied. There is a pool party complete with music I can hear in my room and light show and everything even though they directly told me this would not happen. I call front desk demanding a new room, and they say my only option is to go higher. I agree, pretending not to know how SOUND works. They move me to the 68th floor and I specifically ask if my key will work because I am exhausted and don't want to mess with them. They tell me my key has been transferred. Incompetence strikes again: my key doesn't work. Exhausted, I go to the phone by the elevators and ask security to let me into my room. FIFTEEN MINUTES LATER this woman waddles around the corner and acts all inconvenienced and after another five minutes of mumbling into her lapel microphone, lets me into my room. I can still hear the stupid pool party. Seriously.... how do these people not get inundated with complaints every night? All day Sunday is another pool party distinctly audible in my room, so no nap. I am miserable all day and physically becoming ill from exhaustion. No pool party on Sunday night and I sleep twelve straight hours. Checking out on Monday, I spazz out on the poor manager about my VERY UNSATISFACTORY stay, and he offers to take off the TAX on my paid night. THE TAX. Seriously... screw this place. Maybe it is different on the Bellagio side, but 60 hours without sleep is too much. There should be a warning on the website saying "WARNING: ANY PICTURES OF BEDS ARE FOR ARTISTIC PURPOSES AND ARE NOT MEANT FOR ACTUAL SLEEPING". Since here is no warning, I am providing it. Don't book at the Cosmopolitan if you are expecting to sleep. If I ever step foot in there again, it will be because I have been dragged there by an asian supermodel who has promised to let me defile her. You're welcome.
