It would be enough if you limit yourself to using $300.00 a day for each of the ten days, and leave the casino if you lose the $300.00 in any of the 10 days. Were you to double the $300.00 in any day of gambling, leave the casino and go out to a nice dinner and then go to a Vegas show. This is how to have fun in Vegas and not throw away your money by giving it to a casino. Walk away from the casino as a winner, rather than as a loser. Don't drink too much alcohol while gambling as you'll have the tendency to follow your losses by betting more. Get at least 8 hours of sleep each night so you're more alert when you gamble. $3,000.00 is enough only if you can afford to lose the entire $3,000.00 and not affect your financial obligations or the financial obligations of anyone else who may be dependent on you for providing money or support, such as your immediate family.
