I camp every year in south west Scotland. We take chemical loos with us, and get our water from the tap at the farm gate. It's on a little bay, and it's great...when it doesn't blow or rain! Still, I go every year, for at least a week, as it's the company I enjoy!
I tend to use a lightweight family tent - I have to be able to put it up on my own. I use a larger one if there is someone with me, or if I've brought the dog with me and I can get help. I also just invested in a smaller one for weekend work, such as morris weekends.
