Thanks Spartan for the update - really useful. I wonder if the facilities will be any different for CarFest South (she says hopefully)?
I've been to Carfest South in a tent for the past couple of years. The camping field has flat bits and a hilly but I believe they've changed things around this year so that the car park is on the hilly bit (I think). The motorhome bit has been on a flat bit previously but I'm not sure what they're doing this year. Mrs Two Pints (who knows about these things) says there are about 400 campervans/motorhomes this year!!!
Toilets do deteriorate over the weekend but last year I found the showers to be excellent. I think they come in a variety of shapes and sizes but the ones I had were like having a bathroom to myself! Never seen a shower like it at a festival before. My tip would be to avoid the showers first thing, go to the festival and pop back during the day for a shower. You should have your pick of them by then.
Whether or not the music is what you want is each to their own. We don't just go for the music, some bands we like, some we don't, some are great, others are bands that we wouldn't have seen unless we'd been to Carfest and really enjoyed, it's just a great atmosphere.
The music at South seems OK, Kaiser Chiefs, Paul Heaton and Jacqui Abbott and Olly Murs on Friday should be good. On Saturday, if you haven't seen Seasick Steve before, you might be in for a surprise and The Jacksons will be fun.
Sunday looks OK, but nothing that stands out. Texas are always good value and Marc Almond and Rick Astley will be good if you're of that era too.
We're not really into cars, they charge up and down the track all day so you can wander along and watch for a bit before going off to do other things. If you're there for the whole weekend, I would suggest taking it easy, you'll easily get round the lot during the course of the weekend so we take things leisurely and wander down to the festival when whenever we're ready without rushing.
I hope you enjoy it. We always have done.
