Not sure on all your questions but the 2 times ive been i've paid money at the entrance (Couple of quid that all goes to charity) which gets me the moustache to gain entry.
buy a power bank, anything over 20,000mah will last the whole festival (wifi, bluetooth, app notification off).....don't waste good festival time queuing or having your phone charged somewhere
Yeah there will be spare seats so just get on whichever you like. Personally wouldn’t leave the festival early though unless you have work or family commitments. 1pm seems the perfect time so you can fully enjoy Sunday night/Monday morning
Can't see you having any problems.....people do it every year. I know people who have purchased and got in fine and also people who have sold (person buying got in no problem) If its someone you know just take some form of ID from them as well
Those places you mentioned didnt have anything on the 2019 line up either. The line up is still on the website and can be checked. There will be music just like before
I only used my card in 2019 and had no issues. The phone signal connection will be even better this year so expecting the same. There's cash machines on site if really needed.
The best alternative is to take a collapsible wash bowl that fits in a camping bag (costs a few pound from the likes of b&m). Fill it up with water once awake and have a proper wash outside the tent. 100x better than any wet wipe. Makes you feel fresh and ready for the day
Did it my first year and then realised you just end up missing the entertainment in the early hours being sat at camp. I'm sure there was a designated camp fire area in my camping field 2019 so maybe they would rather than that people outside their own tents.
Shouldn't be a problem getting space at that time
Interested to know who you're wanting to be near the pyramid? Very unlikely you'll be at that stage all day and if you are then you're probably doing glasto wrong as there's so much to do and see. Also there's like a whole new festival after the headliner finishes at the pyrmaid stage....you still have 8 hours of music elsewhere.
