Didn’t stay here - gambled though!
Great games/slots! So many different ones then other properties offer. Drink service was amazing and never a wait. Very attentive. They were also very much implementing Covid precautions. Restrooms were clean and social distancing between machines. They have lots of games that are old and lots that are new.
Just returned from the Cosmo
Great time. The employees are really busy cleaning everywhere. Yes they are on you to keep your mask on correctly. GOOD! They are also wanding people who enter the Cosmo on Fri and Sat nights. Only hotel guests, identity card members or people with a restaurant reservation are allowed in. Also there is a lot of people complaining about groups of people with scooters taking over. Not here, I watched as the doorman turned away a group of young able bodied drunks all on scooters. I saw someone give a 1 star review over it...... They are keeping alot of the trouble out of the building. PERFECT! I would think people want to feel safe during their stay and this helps big time. Gaming floor drink service was great. Ate at the Henry, Lardo, Hattie B, and secret pizza. All wonderful.
this is the place to stay in vegas
I usually stay at the mandalay, or Aria, but the cosmopolitan beats them all for style. It doesn't have the best pool, but everything else it wins with. The location is mid-strip the bars are excellent the rooms are really nicely decorated and the restaurants on site are brilliant (STK)
So this is usually one of my favorite hotels ever but I highly suggest not coming here during covid. Everyone is on a power trip to yell at you for anything. Pull you mask up pull it down. Sit down to order a drink or stand up to order a drink. It is absolutely ridiculous!! Came for our anniversary and wish we would have went somewhere else besides Vegas. Hope they make it through this but we definitely won’t be back for a while. STK Steakhouse on the other hand did a wonderful job of taking care of us😎
Wanded For Weapons to Enter at a 5 Star Hotel?!
Wife and I just got back from a weekend at the Cosmo. Picked this place because of the balcony room over looking the Bellagio fountains and 5 star rating. The room was awesome. The view even better. The service was great too, no complaints at all. So what is the problem... The other guest. This place is bad... really bad. Right off the bat red flags were raised. The people in front of us checking in paid in cash. Didn’t think that was possible at a hotel. At night, there is a huge line of people waiting to get in the hotel. Why? Because you have to be wanded for weapons to get in and only hotel guests can enter... unheard of at any casino hotel... especially a 5 star hotel (do you think the four seasons is wanding people?) That is horribly unsettling. Then you ask why... because of recent fights and/or shootings. Wait what? No thanks.
