As this will be my first ever Glastonbury, anyone got any tips?
Try and get there before the music starts and, before you get completely off your tits, take maybe half a day to do a full circuit of the whole site (preferably in daylight). Not only will it give you a sense of the overwhelming variety of stages, entertainment, traders and food, it will help you get your bearings when its dark and you are off your tits.
In particular note things like the HV pylons that run east-west and the Old Railway Line which runs north west to south east. Other things that can be seen from a distance day or night are the Ribbon Tower in the Park to the south of the site, and the neon Worthy FM sign to the north.
Some folk can get a bit overwhelmed, especially after dark, but the stewards for the most part are lovely and will always offer directions and help. Loads have been volunteering at the site for many years and will know every blade of grass.
What sort of time you have will depend on what you are in to - if you want to park your arse in a camping chair in front of the Pyramid for the weekend that's up to you (many do) but never underestimate the smaller and non-music stages - it is where some of the best times can be had - Avalon, Glade, Leftfield, and hell, even Poetry and Words have all been fantastic over the years. And if it is just too hot or too wet, or you need a little lie down to recoup before the evening gets going again, the Cabaret tent is perfect.
Finally I would say don't stress about not being able to do everything you want to. Crowds can make traversing the site difficult, especially if it is wet, so you will almost certainly miss out on some stuff you might have liked to have seen. Just be willing to abandon your best laid plans and dive into a nearby venue or stop off en route if something catches your eye or ear.
