"When we arrived the Cosmopolitan did not have our prepaid room available and wanted us to stay in a cheaper room for just one night. The next day we got the same story - no room. A manager offered us a partial refund but said it would take 'a while' since we booked through a 3rd party site. Once we left the property the manager stopped responding to email and we have not received the promised refund three weeks later."

"My stay wasn't terrible, but it was not the experience I was hoping for. Front desk staff were very rude and acted like we were bothering them any time we approached. I splurged for the fountain view balcony room and although grand overall the room was very banged up. To the point that I felt the need to take a video of everything, so we didn't get charged for damages. There were marks and scratches on the walls, dirty furniture, cigarette burns on the balcony furniture, balcony furniture was dirty, scratched mirrors, banged up baseboards, chipped glass tops on tables, torn wallpaper, and the glass on the balcony was disgusting. Overall, the room was pretty run down. On the upside we had a great view and the bed was comfortable. I wanted to report the issues, but previous interactions with staff deterred me from doing so. Even bartenders and dealers were rude and displayed an "I don't want to be here attitude. The only dealer I had that was pleasant was my last afternoon there, we almost made up for my other dealer experiences. For the most part the stay was fairly disappointing because I had always heard how "fancy" cosmo was. This was a birthday trip that I had saved for and as a single mother, it is hard for me to find the time to take trips like these."

"All too often people only leave reviews when they have a gripe, so I specifically wanted to make sure I left a review of my phenomenal stay at The Cosmo. My partner and I stayed here as our main home base on our trip to Vegas to get married and attend Wrestlemania and were blown away. The room was comfortable, clean and with an insane view. As a mgm rewards member check in and check out were seemless without even needing to visit the check in desk. We chose Cosmo as it had so many of the places we wanted to visit and none of them disappointed. Weather it was Eggslut in the morning, Block 16 for a quick meal, or Illy for our tipsy midnight snack every place we visited was great. My wife got her hair done at the spa for our wedding and they knocked it out of the park, we loved working out at the gym and relaxing at the Boulevard Pool. My only negative is staying here will likely ruin your perception of what a vacation is as I'm exclusively obsessed with how soon we can plan to return."

"While in the Cosmopolitan Hotel on the Vegas Strip Ms Dayanba Gralonfo the spelling may be incorrect . I believe she was security. She was so sweet and helpful and when we needed an Uber and when my account wouldnt work she helped me set up a new one. I was a little panicky and her willingness to help was such a blessing. Thank you sweetie for your kindness!"

"Checked in for four nights in early April 2026 and was helped by an amazing agent named Cherry (who was not wearing her name tag lol). She provided all our requests and was so pleasant to deal with ...a truly great start to our stay and one of the reasons we will continue to frequent the Cosmo. All the agents were so helpful on this trip and the room was just what we asked for but it is in need of a refresh which is coming next year. The slots were o.k. with a couple of nice wins to keep our heads above water. I really miss some of the older machines but I guess it is what it is. Thanks Cherry and Cosmo for some great memories.
