OK, have to bite the bullet and ask a frank question about porta pottis... interested in advice from a female perspective.... My husband and I have young twin boys. We are completely new to camping and have just bought our Cali. We plan to buy some sort of portable loo. Maybe less of an issue for the 3 men in my life but I don't fancy trips across muddy fields in the middle of the night to go to the loo. What do people recommend? Do we buy a port potti or another brand? Where do we buy from? Do we need a pup tent or can we use a couple of wind-breakers that you see on a beach for a bit of privacy (I think I saw this one a campsite recently). Any other advice on the toilet question would be most grateful. Thank you.
