Tipped:  $20 Upgraded to  Terrance One Bedroom - Fountain View  from  Terrace Studio 

Didn’t target any clerk. Check in on 12/24 Christmas Eve. Arrived at about 8pm. There was a huge line in front of the reception desk. Even thought the web site mark everything sold out, we still gave a try. Hading over a 20 dollars sandwich, we asked whether there was a complimentary upgrade available. She was very polite and offer us an upgrade immediately.
Great experience here at Cosmopolitan.

Checked in around 12:30 PM on Monday, and there was no queue . Couldn’t target a specific clerk, so we got a young and sweet lady. I went forward asking if it would be possible to get a complimentary upgrade, and she mentioned that the room we have is already quite nice, but she’ll still check for us. After checking, she told us that unfortunately there weren’t any complimentary rooms available, but we could spend $85 per night to get a terrace suite fountain view upgrade. We didn’t find that really appealing, so we stayed with our one bed room without paying the tip. However, the room we got was on the 58th floor at the Chelsea tower and had a stunning view of both the Bellagio fountains and Eiffel Tower! By the way, a couple next to us seemed to have got an upgrade with $50. Super awkward when our clerk told us that there weren’t any complimentary upgrades while the other clerk next to her was putting his $50 tip in his pocket.

No upgrade available, despite attempt to tip with $20 trick and having communicated with concierge pre-booking about three requests, none of which were available for check in. Concierge service gave us free buffet tickets for our trouble, which was nice. All in all $20trick does not work here.

Marriott Titanium Elite member (top tier status) and used the Autograph Lounge for check in. Was hoping for a 2 bedroom suite or a fountain terrace at the very least. Tried a $50 sandwich and the agent was super awkward about it. Kinda just ignored it at first, then I asked if any upgrades were available. She made a call and gave me an offer to upgrade to a fountain room for $45 a night or a 2 bed suite for $150/night. Pass. Kept the money as well. Horrible service throughout the stay as well, and later asked a manager for an upgrade due to elite status, they basically told me to pound sand. Very disappointing as the hotel was at low occupancy and rates were very low anyways.

Tipped:  $40 Upgraded to  Terrace Studio - Fountain View  from  City Room 

The Cosmopolitan does not allow you to pick a check in clerk, you go with whomever is available. We had a very nice lady when we checked in around 10:30pm. I put 40 dollars in my passport and asked if any upgrades were available. She immediately separated the money and got on the phone.

Unfortunately, no room upgrades were available, however she did move us from a city view to fountain view. I say no upgrades because this is what the clerk told us. She also gave us a $50 room credit.

It was worth the attempt as the lady was kind, courteous and willing to give us a room credit.

Didn’t say anything, guy knew what was up and appreciated it. Went from standard 2 queen to a 1 king and pullout couch. The upgraded room was much bigger and came with a balcony.

First time in Vegas. Checked in around midnight on a Thursday night. No clerk targeted. Gave the clerk $40 in between my license and credit card and said we would appreciate if there were any complimentary upgrades. She made a phone call and said no but did hand me back the cash.

Went to the Cosmopolitan twice and tried the $20 trick both times. The first time the front desk guy said i left my $20 at the desk. Because he didn’t even check for available rooms for an additional fee, i took my $20 back. I went back a year later and thought i can try again. This time she called someone for them to say the hotel is overbooked. I just took my room key, thanked her and walked away. Dont waste your money on the tip trick.

Arrived around 430pm for checkin on Sunday June 23, 2019. No option to pick a clerk, just had to take thee next available clerk. He seemed pleasant, young man so we went for it.
Sandwiched the $20 and asked if any complimentary upgrades or bonuses were available. Said he’d be happy to check. We had booked a Terrace one bedroom fountain view which was already a decent level room, not many categories above this and honestly this is the room type we wanted for the view, etc but figured we see how this went and what we may be able to get. He did some typing, made a phone call, the whole deal. came back that at this time there weren’t any room upgrades, but he could make sure we got a high floor, and that he’d apply a $75 credit for food/beverage to our account. This was great, a win to spend $20 on the tip for $75 in credit. All was well and we had a great stay. Upon checkout though there was no $75 credit on our account. Tried to get this rectified at checkout, but to no avail….agent and manager said simply they don’t provide complimentary upgrades, or credits. Its not something that would have been done…and as I had no paperwork confirming this I was out of luck…and of course that clerk was off the day we checked out. So a great stay ended on a very sour note. Ended up getting nothing for the $20 tip except some anger and frustration.

If you are visiting Las Vegas and are staying at the Cosmopolitan Las Vegas Hotel and Casino, we think it’s worth trying the $20 dollar sandwich trick. When checking into your Cosmopolitan room, put $20 dollars between your ID and credit card and ask the clerk if there are any complimentary upgrades available. At many of the Las Vegas hotels you can get upgrades to suites!
