The Good : the first one, the setting, the friendly crowd, the music, sun going down over the Sussex Downs.
The Bad : 1 hour wait for buses, then 4 hour wait for wristbands to get in, no information on band timings unless you purchased a lanyard, chaos of the buses after the event and taking 3 hours to get back to Brighton, not enough toilets, few security staff, the terrible app the organisers provided.
