Last time I camped was 2019, but back then there were sockets in the permanent shelter in the middle of the campsite where people took turns to charge sh*t. Never had to wait for a shower, or toilet. Swam in the lake every day. Outside alcohol banned in the campsite, but no one is checking if you filled a water bottle with vodka/gin etc. from the supermarket 15 minute walk away. Also the last year I went security were letting you walk across the bridge from the camp island to the festival island with a plastic pint glass full of whatever was in it. Went alone both times I camped and made some good friends both times. Would recommend. Felt safe to me, so few people camp you get to know everyone quite quickly.
Feel free to ask more.
