Sin City.. Excllent Choice You will find plenty to keep you occupied, Plan on going down with a comfotable amount of cash, whateer you think is comfortable, play it smart, play fun, But remember gambling isnt the only thing to do, Remember when you do gamble you do get free drinks, but its not the quickest service ever, its always best to play the table games and you will find that you will get drinks quicker.
Now apart from the gambling there is much to do.
At the NewYork NewYork Hotel there is the Coyote Ugly bar, which is free cover before 10pm, after that is 10 dollars which is the cheapest cover in Vegas Pretty Much, Most clubs are goign to run you about 20-40 Dollars cover, and thats if you can get in, and they dont open till 11pm and go till 5am. of Course they are Dress Down, So you have to wear appropriate atire. Also There is teh Rollercoaster You can ride for like 8 bucks before peak hours.
The Bellagio & Treasure Island.. Both have free shows you can watch.
Inside Cesars Palace you can go to the Forum Shops and there is also a Free Demo Show inside.
Walk the Strip you will find plenty of amauzements to do
DownTown on freemont street at night they have the Laser Light Show on teh Half/Hour Begining At 9 or 10, depends on time of year.
If you want strip clubs, and want a good time, Go to Glitter Gluch, Its downtown on Freemont street, the classic Light Up figure sign of the Girl swinging her boot, It is free cover but there is a 2 drink minimum and Domestics will run you about 8 dollars a piece, but in the long run it is worth it and cheaper than most covers at strip bars.
If you arent 21, or dont have a FULL proof fake id, you arent going to be able to do all of the adult activites as they are really strict, and of course depening on where you are. But there is wet n wild waterpark, the stratosphere tower, and other amuzements for all ages..
Enjoy..
