After booking a room at the Cosmo for 3 nights and checking out the hotel website, I was definitely pumped to stay at a top of the line, new hotel located directly in the center of the Las Vegas strip. \n\nAs other reviews have mentioned, this hotel IS swanky. The furnishings are nothing but chic, the chandeliers are massive, the bedding is lovely, the bathrooms are brand new and furnished with nice shampoos, conditioners, lotions, etc. As for the hotel itself, I was definitely impressed. \n\nAs for the customer service...well, that's another story. You'd expect a premium 5 star hotel on the Vegas strip to offer nothing but the best in customer service and satisfaction. Unfortunately, the service was not up to my expectations when it comes to a 5 star hotel. \n\nWhen I checked in with my boyfriend for a 3 night stay, we were informed that the hotel has a DEPOSIT of $150/night. Seriously? I understand that a deposit is necessary, and many hotels have a deposit requirement, but $150 per night is a bit excessive. We told the front desk clerk that we had a late flight out. She told us to just call downstairs and request a late check out, and that it shouldn't be a problem.\n\nThe morning of our departure, we called downstairs to request a late check out. We were informed that any check out after 12:00 noon would be charged for a half-day's rate. What? This was not communicated to us on check in. What seemed like it wouldn't be a big deal was clearly an issue for the hotel. After attempting to negotiate, we were able to get a 1:00 check out. A whole 2 hours? Gee, thanks. The icing on the cake was when a hotel employee knocked on our door at around 11:30 and told us that we were late checking out. After calling the customer service number and complaining about her treating us like children, we did not receive any sort of solution other than an apology.\n\nOverall, the hotel itself is lovely, the customer service is lacking. Try somewhere else.
