Finally stayed at the Cosmo. It's always been over my comfortable price range considering we like to stay in Vegas for 4-5 days usually. At $300/night that's a big expense for most. However during this summer we got a 3 nights for 2 at already reduced prices so I went for it.
Overall I'm glad I stayed here and would stay again. It is very expensive. This is a top-tier hotel on the Strip no doubt. With Marquee dayclub & nightclub, fantastic restaurants, beautiful people and architecture, and a breathtaking view off any balcony suite - it ranks next to Encore as my favorite place to stay.
People say why spend money on a room when you're only going to be in it for a few hours to sleep. I disagree. We want it to be a home away from home. We want luxurious furnishings, amenities and fixtures with a large double-sinked bathroom and shower big enough for a party. I'm sad I didn't get to try the jacuzzi tub - I will next time. For me the balcony is the top draw. Why other hotels don't have balconies in Vegas is beyond me. Palms Place locked their balconies which will be the downfall of that hotel.
Make sure you visit the Chandelier bar at least once. Drinks are pricey so choose wisely.
We also decided to go out to the Boulevard Pool. Originally we were only staying for an hour or so. We loved it so much we got a daybed and spent near $300 on margarita pitchers and food. If you get a bed, remember they automatically add a 21% gratuity to the bill. Not that bad, but read your receipt before you add another 20% by mistake. Also unless it's a really hot day, don't sit under the misters or you and your things will get soaked - one of the reasons we ended up getting a daybed.
Love the Cosmo. Didn't like the slots. They aren't loose at all and I tried a lot of them. Save your money for another casino but come to the Cosmo to feel like a millionaire in their elaborate rooms.
