Pro's Free ticket and campsite resembling a ski slope to camp on. Getting to know some other stewards and performers.

Con's They really want their moneys worth of hours out of you. Working hours often don't coincide with performance times so you miss THE events you really wanted to see. Ticket does not guarantee entrance to any event. Sometimes having to choose between eating and getting to an event. If you end up in a marquee on the hillside you can be eating burgers in thick cloud for a week, not my idea of fun.

I have bought tickets, stewarded and gone without a ticket and paying to see events I particularly want to attend. The last is definately the best fun and much, much cheaper. The money saved can be spent on booze.
