Some of the easiest comps to get on the Las Vegas strip are drinks. At most casinos on the strip, all you have to do is gamble for a few minutes before you are offered a complimentary cocktail. If you are standing at a table but not playing, you will likely not receive a free drink, and the dealer may ask you to move to make more room for other players.
If you have a high budget, you can play in the high stakes areas of casinos on the strip. The high stakes area is where the "high rollers" come to play. Table minimum bets are between $300 and $500, depending on the night (usually it is a higher minimum bet on weekends). However, whether you win big or lose big, casinos will usually give you a room upgrade or comp a suite when you spend a lot of money at the tables.
Most casinos on the strip offer a Player's Club, which you can sign up for in person or online. There is no charge to join. When you become a member of the club, you receive a plastic card with your member ID. Ask the dealer or person changing money to swipe your card, which keeps track of how much you bet. Usually, the card only counts bets of $25 or higher. Once you reach certain limits, you qualify for predetermined comps, like room upgrades, free meals or limo rides.
Tipping is a good practice in Las Vegas, especially when you are trying to get comps. Tip your cab driver, bellman, dealer, waiter and anyone else who accepts tips. They may offer you comps in return. For example, many cab drivers have free passes to clubs or other events that they are more likely to pass out to passengers who tip them well. Bellmen have similar comps to pass out to pool parties or VIP lines at the clubs in some of the hotels on the strip. A few extra dollars can go a long way in getting comps given to you.
Sometimes, you just have to ask to get a comp. Ask your concierge for restaurant recommendations, and ask if they have any comps for nearby restaurants. Restaurants often give concierges comps for a free meal or a discount to entice more people to eat at their restaurants. Casino hosts and pit bosses are also able to give out comps. If you have been playing for a while, ask the casino host what they can give you. Most likely, you will get something out of them if you have been playing for a while, whether it be a free meal or a room upgrade. Be polite; the worst that can happen is they say "no," so it never hurts to ask.
If you like to stay at a particular hotel on the strip, email or call the hotel manager in advance. Let them know you stay there often and plan to stay there again. Most hotel managers like this kind of feedback and are happy to offer small comps upon your next return, like room upgrades or free rides to and from the airport.
You might also receive comps when you check out of a hotel. If you have been charging meals and other services to your room, ask the hotel front desk or manager when you check out if they can comp anything from your stay. They may be able to take off a meal or a drink if you have stayed for a while and spent a lot of money. But do not count on it; only purchase what you can afford in case the hotel decides not to comp you anything when you check out.
