Arrived at TI and had a $20 sandwiched between my ID and credit card. Was called next in line, was asked for my cards and gave the receptionist my sandwich. I immediately told her it was our anniversary and asked if she had any complimentary upgrades. She said “sure, let me check.” What threw me off for a second was when she asked when we got married. I was nervous enough about the sandwich trick and now I had to remember the date immediately! Thankfully I remembered right, just something odd I thought she asked, maybe just to see if they tell you the truth. We were finally offered a strip view from the 30th floor, a free bottle of champagne delivered to our room, and a ton of coupons which included 2 free buffets. I do wish we got a bigger room suite, but the standard room was still nice and the view you can’t beat! All in all, worth the $20. Next time I’m going to specifically ask for a Tower Suite though.

Did the sandwich with a $20 bill. Immediately was offered an upgrade to a larger suite with 2 bathrooms and a jacuzzi. Mentioned it was my girlfriend’s birthday and they sent us some champagne. Great value for $20.

Checked in on a Friday at 6pm. Got upgrade to suite room and they sent free champagne to room. Told clerk it was birthday weekend and asked for any complementary upgrades. Had $20 under ID as soon as I walked up to desk. Very helpful.

We were upgraded to a fabulous strip view room when we made the $20 sandwich! I think we might have gotten a better room if we’d only needed one king sized bed, but we needed to have two beds to sleep the four of us. We also got a free bottle of champagne (cheapest in the room service menu was $32). We felt like we got some good things from our $20!

3pm check in time – slipped $20 in between card/id asked if any upgrades available, was chatty friendly – was given two free buffet coupons, bottle of champagne, upgraded to a strip view room with view of the Siren’s cove, 2 for 1 drinks at Kahunaville.

We checked in a 2pm. In the line I was looking for fresh clerks that were just about to start their shift. There were several on the right side of the check-in desk, while most of the people were going to the tired clerks on the left side. Once my line came up, I stayed on the side for a bit until the needed group of clerks opened up and went straight to them.
I handed the guy my sandwich (I decided to tip $50 since my stay is 1 week long, around $1100 total) and quietly and politely asked if there are any complimentary upgrades. He asked me if I wanted any specific room, and I asked for something nice, since me and my wife were on the honey moon. He was so nice and gave us the petite suite (much larger room with 2 bathrooms). Unfortunately, the first one was overlooking the construction site, so I went back with the keys and asked him if there is anything overlooking the strip (didn’t need to tip this time). In less than a minute I had the new keys. Such a wonderful beginning of our stay!

Gave the clerk my $20 sandwich (credit card and military retiree ID card) and asked if there were any complimentary upgrades. Clerk discretely put the $20 aside and started tapping on his keyboard. No bigger room was available, but he gave us a room with a Strip view, and right above the TI Sirens pirate show. Plus, a bottle of champagne was delivered to our room.
This was in 2012, and I understand the pirate show is no longer running.

Checked in at midnight.
Handed in the sandwich but I did not say anything, thought the front desk lady would at least do something about my room.
Turned out my money was gone but I got a shitty room, smell like 200 people had a smoking party last night and charged resort fee.
Worst $20 I ever spent.

Got the next clerk in line (younger male). Checked in about 3pm. Did the $20 sandwich under my license and told him it was our anniversary (it really was). Got upgraded to a strip view on the 33rd floor. We were staying for 5 days, so the difference in room costs would have exceeded the $20 if I had paid for the upgraded room.

checked in about 11am. Put the $20 between my card and license. Our room was already comped. Got free early check in, late check out and a bottle of bubbly for the $20. The check in/out extensions are normally $30 each.
