Didn’t use the self checkin, but the regular queues. Which took quite a bit.
After handing over our international passport with 20$ inside it and the credit I asked if there are any complimentary upgrades available.
The lady simply told me “we don’t do that here” and gave me back my 20$. No success though only staying for 2 nights.
Had success at the Excalibur some days before with 20$ on even a 4 night stay.

We came in late about 6PM on a weekend. I didn’t really expect anything coming in, but I REALLY didn’t expect anything when the hotel had a lot of self checkin kiosks with a few attendants walking around. I decided to try nonetheless. Requested assistance via the kiosk and waited for an attendant. She came and we tried slipping her the sandwich with the line. She saw it right away and said she didn’t need it and only took the ID. We then asked her for conjoining rooms. She went away for a couple minutes and was able to get conjoined rooms but no upgrade. She didn’t take the 20.

Quite a bit of people checking in so we just picked a line, got a younger Asian dude, slipped him the sandwich w/$20. I said ” a friend on mine said I should ask if there’s any complimentary upgrades on the room.” he said “sorry its too late in the day (9pm) I wish I could ” pushed the $20 bucks back to me. It was worth a shot

Gave clerk the sandwich (young male late 20’s). He split the ‘wich apart, putting my dl and cc on the keyboard and laying the $20 in the counter beside his keyboard. As he was doing that I asked if there were any complimentary upgrades available. BEFORE he looked at his computer, he said, No, we don’t do that here.” After he looked at his computer he said, “You’ve already booked a (MOnaco) suite.” Umm, yeah, but I wanted a Diamond suite! Oh, and he proceeds to say he has a suite on the 3rd floor or if we waited 15 minutes we could have one on the 13th floor. What hotel has a 13th floor??? He bundled up the sandwich and handled everything back when he was done with my dl and cc. back the $20

Reserved standard deluxe room for 2 nights. Gave the guy a $20 and asked for something nice. Gave me a high floor deluxe with pool view and a fridge. Gave me a bunch of coupons and club passes too.

We had 5 rooms at Park MGM for 4 nights. I tried the trick with $200 as we were so many and requested for the resort fees to be cancelled. Resort fees would be about $175 for each room (about $45 per night per room). That’s approximately $875 for all of us.

With this $200 tip, I got all the resort fees cancelled ! That’s a $675 saving !

We actually stayed at NoMad hotel but there was no select option for it so we put park mgm since they are in the same hotel. We got upgraded from the classic queen to a double salon. I guess this would be a queen suite(?)There were 3 people at the concierge but the young lady greeted us first so we went to her. It was about 4pm on a Sunday and once we slipped the 20 in she said she was just about to ask if we wanted complimentary upgrades. It seemed like it wasn’t her first rodeo and was more than happy to help us. She said that our room was the best she could do for us at the moment and honestly I couldnt complain. I was just excited the little trick actually worked!

Visit during a busy January weekend, the hotel was packed with Hockey fans so was feeling a bit underwhelmed that this wouldn’t work. We did the sandwich to a lovely young member of staff who was awesomely cheerful and friendly.

The Monte Carlo (Park MGM to be soon) is undergoing renovation and we had our room upgraded to one of the few newly refurbished Park Rooms which was great and much nicer than the orginal room. We also received free comp drinks for the in-house restaurant.

For saying how busy the site was we where impressed with our upgrade without even mentioning it, just the sandwich slip!!

We had a nice connection with the desk agent, she was Canadian like us, but oops, made a comment about Trudeau and Trump, turns out she loves Trump. No upgrade, no resort fee discount, at least she gave the 20 back.

Checked in around 1pm on a saturday. I was a bit apprehensive given the fact that monte carlo has a very low success rate for the trick but i thought id give it a go anyway. Got a female clerk in her mid 20s, figured she looked young and might hook it up. I put on my biggest smile and slipped her the sandwich and asked if there were any complimentary upgrades available. She took the sandwich, saw the 20, took it out, and said, “aaand you can have that back, unless you were planning on giving it to me”, which took me off guard. I was a bit nervous doing this anyway because i HATE rejection, and said oh, thanks, and took it back. In hindsight i shouldve said something smooth like “it depends on if there’s any upgrades” but I just sensed she thought I was retarded and a douche for trying (probably my insecurities LOL). So, yeah, didnt work for me…
