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.

Chose clerk furthest from manager.
It was 5pm.
Gave her the 50 sandwich and asked if there were any upgrades available. Told me that for 80 dollars I could upgrade. It usually cost 100.
I declined. She kept the 50 and said thank you.

Handed the $20 “sandwich” to the check in lady and asked if there were any complementary upgrades available. She made a call and said we can give you a wraparound terrace suite. We happily accepted! Check in was around 11 pm on a Friday and there was no one else checking in when we there.

Gave the 20 sandwiched between license and credit card. Clerk asked if I needed change. I replied that it was for checking if there were any upgrades and that we were celebrating wedding anniversary. Clerk indicated that they can only take tips and they will check and we are free to take tip back if we want. Clerk checked around and found a great upgrade for us – newly renovated Terrace Suite Fountain view.

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!

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.

We arrived at midnight with 3 adults and 2 kids. There were only 3 front desk attendants. I put the $20 dollar tip between ID and visa. The lady was very polite and put the money besides her computer and asked if we wanted change? I said slowly with my poor English if “I could get a free room upgrade?” She said she will see what she can do. She then called someone and was able to get us a room with two bedrooms, a living room and two washing rooms! The rooms had 2 queen beds and one king bed and she added a free crib so everyone could have a bed, which was fantastic! It’s our first time to las Vegas and it’s such a wonderful room. Thank you for the kindly lady and this helpful website! Good luck everyone!

I checked in on at 6pm on a friday night. I handed my $20 dollars between my ID and CC and asked politely if they had any complimentary upgrades and also mentioned that it was my first time staying at the Cosmopolitan. The clerk placed the $20 dollars on her keyboard and started typing and let me know that she would see if anything is available. It took awhile and she even called someone on the phone asking what she could do for me. I ended up in a terrace studio which was amazing and was much better than I had expected as I booked the lowest room type.

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.

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.
