Me and Liz went along to Sonisphere in Knebworth this year, got a weekend ticket each and, luckily had a friend from Hatfield also going, meaning we could get a lift in each day and not have to camp (Liz is mostly against camping). This did mean longer trips there and back each day, as well as a long walk to/from the car, but it was nice to have a comfortable bed to go back to in the evenings (and non-smelly toilets, which was the main bonus for me as I like camping otherwise).
