1) it shouldn't really matter which is closer, there's also probably no way to tell yet. (the island is also tiny) 2) yes you can pay extra for nice toilets, showers, and a USB charger/Locker 3) unsure about shower opening times but at every other festival I've been to showers are 24/7 4) think there is only ferries/hovercrafts back to Portsmouth/Southampton 5) it's a prime time for the ferry I'd say so yes, the ferry company suggests you get there 30mins before departure time so I'd suggest the same! Hopefully you have an amazing festival!

Your own alcohol in all of the campsites is fine, its just when you try to get into the arena you can't take it, that's where all the bands play. hope you have an amazing festival and are excited as I am!
