Tipped:  $20 Upgraded to  Terrace One Bedroom  from  Terrace One Bedroom 

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.

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.

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.

Tipped:  $20 Upgraded to  Terrace Studio - Fountain View  from  City Room 

Prior to my trip, I read this website. I arrived at 9am (before check-in). I followed the instructions, except I used a $50 in between my credit card and license. She placed the bill next to her and I asked if there were any upgrades available. She stated they were pretty booked. She then made a phone call and stated she could give me 50% off on the upgrade per night. Came out to $25 a night. She also immediately checked us in and put us in a balcony room on the 55th floor with a view of Bellagio fountain and the strip. Room was awesome.

My boss got mad. I actually didn’t know if I’d gotten an upgrade (never been here before) until my plus one mentioned at a work party something about our terrace with the fountain view. lol. No one else had been upgraded including the CEO who was paying for everyone.

Tipped:  $20 Upgraded to  City Room  from  City Room 

Checked in on Monday at 2:30pm for 4 nights into a City view room with 2 queen beds via Allegiant Air booking. Slipped a $20 bill and asked for a complimentary upgrade to terrace studio fountain view with 2 queens. Agent called then went into the back for a bit and came out and said it would be a $45 extra per night or for free he can put us in a newly remodeled room on 50th floor with fountain view. We took the latter at no extra cost and he returned the $20 to us but I insisted he keep it since we were given remodeled room on high floor with fountain view. He was very appreciative and offered us a late checkout for 1:30 pm and he even sent us a box of chocolates. Very kind and nice clerk!

Tipped:  $50 Upgraded to  Wraparound Terrace Suite  from  Wraparound Terrace Suite 

Checked in around 11am on the Monday of July 4th, visiting with a group of friends. We booked both the wraparound suite and terrace studio 2 queens. Couldn’t target a clerk. Young women checked us in she was very nice. I slipped her my cc and dl with a $50 sandwiched in between. I asked if she could give us two rooms on a high floor together. She placed my ID, CC, and bill on the side of her desk very visible. Then she said, “Let me go make a phone call in the back, I’ll be right back.” But then a few minutes and a few key stroke later she says “I love when I’m having a good day and everything works out. I have a terrace studio and wraparound suite very close together on the 51st floor and I can give you partial views of the Bellagio fountains. The terrace studio is available right now, and I can send a rush order for the wraparound suite to be available now as well.” We also had a third person staying in our wraparound. On the website it says that they charge for extra people above 2, but she just asked how many keys and suggested that we should get 3 in case anyone gets locked out! No extra charge.

Early check in, high floor, and fountain views? I couldn’t believe it. She also made it clear it’s nice when people are nice and don’t talk down to the clerks as the cosmopolitan try to be as accommodating as possible. Then once the transaction was complete she asked, “Is this for me?” While pointing to the bill and thanked me very much and says it’s much appreciated. The rooms and views were stunning. Best $50 I’ve ever spent.

Tipped:  $0 Upgraded to  Wraparound Terrace Suite  from  Terrace Studio - Fountain View 

Checked in, didn’t even ask for an upgrade, was told we were getting upgraded to the wraparound terrace suite, didn’t take it too serious, but low and behold it was amazing, totally made our Vegas trip the talking point…..

Tipped:  $50 Upgraded to  Terrace One Bedroom  from  City Room 

Did not target a clerk as there was a line. Checked in around 4:45 and slid the attendant a $50 to see if we could get an upgrade. This was going to be my first gamble of the trip and I lost. Not only did the attendant keep the $50, I ended up paying $38/night for a terrace one bedroom for our three night stay.

Tipped:  $20 Upgraded to  Terrace One Bedroom  from  City Room 

I arrived around 12PM on a Monday. I did not target a clerk because they had us form a line and you had to go to the next available clerk. I walked up to the desk and said “I’m a little early, I was wondering if I could still check in?” She said sure. I handed her a $20 sandwich and said “I was curious if there are any upgrades available?”. She put the $20 off to the side and said she needed to call someone. She called and then got off the phone and said she could upgrade us to a terrace one bedroom for free! 🙂

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!
