I need help with the events plugin

Hi I'm running a three day camp and have created an event, but I'd like people to be able to pay per day in case people can't make all 3 days. At the moment I have the event at £6 per person per day, but people have to just enter quantity of people and number of days, whereas I would like it to be more professional looking. Please advise me. Thank you
