To wash or not to wash.I'm going to confess I'm a "grab a wet wipe, wipe and go" kind of girl.
Festivals are awesome fun. They are in a field. They last a few days. Wash before you leave home, wash again when you get home.
Barring getting covered in piss or vomit there is not really much cause to wash in my opinion. Queueing for the showers wastes time, is boring and costs money.
BUT for those delicate flowers among you, there are showers, you can queue and have a shower every day if you like.
Or you could fill a bucket with water and wash your hair at your tent (I did this at Glastonbury!) refreshing, free and quick.
Don't hog the tap though, do use a bucket, washing AT the tap is very rude! Think of others (ditto when you clean your teeth)
If you plan to wash/shower - remember to take towels!
Children will love getting grubby and not washing (most children) so just let them run free range. Enjoy being at the festival, it's not a place for perfect makeup and nails or hair tongs! It's a place to relax, hear music and drink cider.
