Most taverns will serve something that’s non-alcoholic. There are also plenty of tea houses. My house in Dawn runs a gin and tea house. We have a stash of lemonade and irn bru ( because we’re Scottish), and a variety of flavoured teas. I’ve only got pictures of the outside, I don’t know why it didn’t occur to me to take any of the inside. But we’ve got a couple of tables about 8 chairs, a bar and a stove, and a couple of star gazing chairs for outside seating.
Most of the tents will have some sort of lighting. You can get solar powered artificial flame torches that you stick in the ground outside your tent. They look really cool. Going back to my tea house, decorate the entrance with solar powered fairy lights. We’ve also got some metal decorative containers filled with artificial fairy lights that we line the entrance with. I’d recommend some sort of portable light to find your way around at night, more to avoid tripping over guy ropes than anything else. I currently use a replica oil lamp with an led light in it, but its a bight bright for my tastes, so I may replace it with a soft led lamp at some point.
