Don't drink the water
It's usually very hot in Vegas and hotels are more than happy to provide you with bottled water... for 4 bucks a pop. Rather than pay the high markup rate, stop by any of the convenience stores along or just off the Strip and stock up on enough water for to last the whole trip. After all, the ice is free...usually.

Bring a watch
There are plenty of things to see in Vegas, but one thing you won't see are clocks. The casinos want you stay inside as long as possible so you don't realize how long you gambled so you won't find any windows or clocks on the casino floor. Set the alarm on your watch or cell phone to remind you when its time to leave.

Get off The Strip
If its your first time going to Vegas, stay at a hotel on The Strip. It may be more expensive, but there is so much to see and do on the most brightly lit avenue in America. But if you've partied in Sin City once or twice, check out the many great casinos and restaurants off The Strip and in Downtown Las Vegas like Binion's Horsehoe and the Red Rock.

Swim early (and often)
In the real city that never sleeps you'd expect the pools to be open all night. Not so. Most pools shut down before dusk because hotel managers know that people have a lot better choices than circling the pool all night. A quick night dip is possible at pool parties like the one at The Palms, but don't count on most hotels having this luxury.

Hand over the cash
There are plenty of ATMs to be found in Vegas, but they the convenience fees are a lot steeper than the $1.50 charge at your local gas station. Keep small amounts of cash on you and larger amounts in your room's safety deposit box (not a good idea at shady motels) to have an idea of how much you're spending.

Keep it moving through the airport
This should have been first, but upon arrival at McCarran International Airport, the sights and sounds of ringing slot machines are enticing, but everyone knows your chances of winning at the airport's one-armed bandits are slim to none.

Get carded
If you plan on doing most of your gambling at one casino, be sure to sign up for the casino's players card. The card tracks how much you bet and how often and if you win big or play for long periods of time you could get comped rooms, drinks or free meals. Each casino has their own card but the One Club is valid at the Luxor, Circus Circus and Excalibur, three major casinos.

Get on your feet
Renting a car in Vegas is absurd, especially if you're not planning on leaving the nearby area. Driving anywhere down the strip takes forever and is better seen on foot. If you must travel the length of The Strip, take the monorail which goes from MGM Grand on one end to the Sahara on the other, and several stops in between. Beware that the monorail map makes nearby casinos seem closer than they actually are.

Look but don't touch
If you're not the high roller type, there are many pricey, high end shops at the Bellagio, Wynn, Palazzo and Forum Shops where you can admire expensive gowns and decadent jewels from the other side of the window. If you're not ready to spend some serious green, refrain from going inside or you may get the dirtiest looks you've ever seen.

Bring your lady friends
If you are a group of girls headed to Vegas for a good time, you are all set to get into Vegas' outstanding nightclubs with little problems. But if you are are a group of guys prepare to wait outside. Vegas clubs want to be populated by hot women, so if your group is running on testosterone, find some nice ladies who will go up to the velvet rope with you. This will increase your chances of getting in.
