I usually play the slots and I limit myself to $20. Because I only go to be with my friends and family. We usually go to the casino and then go out to eat afterward. Having said all of that it's been 10+ years since I have been to a casino. None of my family members are interested in going anymore and I don't want to go we just my wife and i.
I usually have a look around and see what's open, depending on the day/time, not all poker tables will be running. You can then decide whether to stay or go elsewhere,
Usually scope out the table games. Other than poker, gravitate to blackjack, roulette, and baccarat; in roughly that order. Oh and I normally order a drink. A G&T or Tom Collins hits the spot.
A bottle of beer and few sticks of cigarettes will put me in the right mode to try my luck. I don't exceed one bottle because i can easily get intoxicated! One bottle of beer is for alertness !
The first thing I do when I get to the casino is to check the games that are available to stake on. Doing that would help me to decide how I am going to manage my gambling budget for that session.
Whenever I want to visit a Casino, I tend to make a brief plan of what I want to do. I allocate the amount of money I am going to spend and determine the games I will play.
