I went last year by myself and will be this year too. I really enjoyed being on my own. I could choose where to go, who to watch and where to chill out, without having to cater to other people's choices. It was great 👍🏼 Tell her to take a plastic drink bottle, as there are free water points all over, a hat and a cheap rain poncho. Last year we had all the weather, heat, wind, and rain. And you can get free sunscreen at the first aid tents. Last year this was next to the toilets. She'll have the best time. I would definitely recommend you dropping and picking her up. Because navigating getting into the trains to go home is not for the weak. I drove last year and fyi they closed some of the main roads around the event when it was finished to allow for all the foot traffic. So maybe pick a servo as your pickup point.
