This will be my 1st time in Vegas. I'm not a big gambler, but will play slots each day (max $150 per day) Staying 4 nights. I'm getting $1000 cash from bank before flying out. I will use cash to make small purchases for snacks/drinks while walking around. All "meals and cocktails" will be paid with credit card. How should I break up the bills.... I will of course want some singles for tips and such.
