I would skip the 10's and get more 5's. You may want to take extra, if there is no place to get more change. You will find that later in the night you will need less smaller bill. It is early in the event when people have the larger bills. Once those get broke they use the smaller bills.
What prices are you charging? Not for specific item just the prices.
