So I'm going to reading festival for the first time next week, I've been searching around trying to find answers to a couple questions but can't seem to find what I'm looking for. I have two day tickets, one for Friday and one for Saturday. The ticket says the site opens from 9.30am but the arena opens at 11am, does that mean that once I get into the site I can go to the campsite and see my friends (who have weekend tickets) before I line up to go into the arena? Or is there a different route for day ticket holders that doesn't go through the campsite? 2) Also, I'm unsure of what time I actually have to leave the site by? Is there a specific time that day ticket holders have to be out by? 3) Lastly, as I'm leaving the site will I be walking through the campsite? If so, would it be possible for me to visit my friends for a while before I actually leave? I know I won't be allowed back into the arena if I do this but is it possible? Sorry there's a lot of questions, thanks in advance!
