The danger of camping in a tent rather than a trailer is the possibility of a loose horse trampling over it. Remote I know, but the safe option is camping in the trailer. Bucket with sawdust/shavings in is useful as a loo. Put food in a cool box with a lid to exclude vermin, and ants, and other people's dogs. An LED lantern is more useful than a torch if you can hang it up with a bit of bailer twine, but with long days and short nights you probably won't need it for long.
I hadn't thought about the danger of a loose horse trampling a tent. My own problems of similar sort have been limited to people wandering around after spending a bit too much time in the beer tent and tripping over guy lines... This year, I'll be taking a string of solar powered fairy lights to put around my tent. (It will help me find my way back to my own tent, too.)
A bucket with sawdust or shavings is a good idea. Even kicked over after use, it will be easy to sweep up.
A head torch is much better than a hand-held torch, leaving both hands free for things like carrying your toilet bag and still being able to open gates...
