the music thing is a moot point if you only like to see 'commercial' bands. We go to many festivals and while we do watch some big names we also like to wander and stumble across artists we've never heard of before. I like all music, not just whatever Radio1/The NME are telling me I should listen to.
There are some festivals I wouldn't take my child to (Endorset for example) but he will be coming to Glastonbury with us in 2013, at his insistence
(he threw a wobbly this year that we went without him)
We're going to Tolpuddle on Sunday (because we're on holiday anyway, a happy accident that it's on while we're there). We're going to Croissant Neuf and Shambala too. And they all have great stuff for kids to do.
How do we afford it? we're lucky that DH has a good job and we don't have hobbies etc and so we spend our savings on having a really good summer full of music and spending time with like-minded people. Many people I know work the festivals so they get a 'free' ticket, and that's how they afford to do several in one summer.
The 'boutique' festivals don't really float my boat, but there are loads of small affordable festivals all over the country, you just have to look for them because they aren't publicised like the 'boutique' ones are.
V, T in the Park et al are my idea of hell.....but that doesn't mean I look down on people who go to them. I just wouldn't go myself.
