I really want to go to Glastonbury this year - I know it sounds stupid but I'm really worried about having to pee. My friends have told me that the toilets are often un-useable and you can get stuck in big crowds with no loo. They've told me you just have to hold it but I don't know if I can - I've got quite a weak bladder and normally have to go quite often.
What do you do?
