What the Sandwich Trick Actually Is
The $20 sandwich trick, sometimes called the Vegas sandwich trick, is simple: you fold a bill so it sits hidden between the credit card and ID you hand over at hotel check-in, then ask the front desk agent if any complimentary upgrades are available. The agent either has the flexibility to move you to a better room, a higher floor, or a suite, or they do not. The bill is a tip in advance for the effort of looking. It has been a Las Vegas insider move since at least the early 1990s and it is still around in 2026, just not in the form it took when a Strip room went for a fraction of today's rates.
The Honest 2026 Update: It Works, But $20 Is Now the Floor
No hotel publishes a policy on it, and nobody can promise a result. What has changed is the math: front desk agents at major properties have seen the move thousands of times, Strip room rates have climbed a long way since the trick became widely known, and $20 means less than it did in 2005. At a luxury resort, a $20 tip reads as a gesture rather than an incentive. The agents are not offended. They have seen everything. But the gap between what you are asking for and what you are offering has to make sense.
If you try it, scale the bill to the room rate. At value and mid-tier properties such as Excalibur, Flamingo, New York-New York, Paris and Horseshoe (the former Bally's), $20 is the traditional amount and still reads as a real tip. At upper-mid properties like The Cosmopolitan, MGM Grand or Caesars Palace, $40 to $50 is the common working amount. At luxury resorts such as Bellagio, Wynn and the Venetian, $100 is where most people start, and availability decides it either way.
How to Do It Correctly
Most people get the execution wrong, which is why they report mixed results. The method matters as much as the amount. Fold the bill so it is hidden between your ID and credit card: not visible, not announced, not accompanied by a wink. Hand everything over naturally. The agent will place the bill on the counter without acknowledging it. This is normal. Do not fill the silence. Let them complete the check-in process. When they ask if there is anything else they can do, your line is: "Do you happen to have anything complimentary available, like a higher floor, a better view, maybe a corner room?" Ask for something specific and reasonable. Do not ask for a suite by name. Do not mention the bill. Do not negotiate. The agent knows the bill is there. The question is only whether the inventory exists to do something with it.
If they can help you, the bill stays on the counter and slides naturally toward them as the transaction closes. If they cannot help you, they will either return it or quietly acknowledge the situation. Either way, stay warm. The agent is not the obstacle. A sold-out Saturday in fight week is.
Timing Is the Variable Nobody Talks About
The amount of the tip matters less than the availability of rooms to upgrade you into. A $100 bill cannot create a vacancy that does not exist. The best conditions for the sandwich trick are: Sunday through Thursday check-ins, non-convention weeks, mid-afternoon arrival rather than late-night, and hotels with large room inventories where agent discretion is higher. The worst conditions are: major fight weekends, CES week in January, New Year's Eve, and busy summer Saturdays, when hotels sell out and there is nothing to offer regardless of what you hand over.
One underused variation: if the trick does not work on check-in day, return to the front desk the following morning and ask again. Rooms turn over overnight, availability changes, and a different agent may have more flexibility. Some guests have gotten their upgrade on day two of a four-night stay and enjoyed it for the remainder of the trip.
What You Might Actually Get
An upgrade does not always mean a suite. More commonly it means a higher floor with a Strip view instead of a parking lot view, a corner room with two exposures instead of one, a newer renovation wing instead of an older block, or occasionally a room category step up. All of these are worth asking for. A Strip view from a high floor costs nothing extra and makes the room better. Set realistic expectations and the trick delivers. Expect a penthouse suite for $20 and you will be disappointed every time.
Before you reach the desk
Whatever room you end up in, the resort fee comes with it, and our Las Vegas trip cost guide shows what that adds per night. If you are shipping anything to the hotel ahead of check-in, our guide to shipping a package to your Las Vegas hotel explains how the front desk matches the box to your reservation. The name has to match exactly. Once you're in the room, our what's happening in Las Vegas this weekend page shows what's on during your stay.
