WRT Laundry Soap - I have found that the soap pods work great for camping. It is a lot easier to carry a few pods to the laundry than a big jug of liquid detergent.
Just keep pods you are about to take to laundry in a sandwich bag just in case you break one accidently.
Also, what about dryer sheets - much easier to use than liquid fabric softener
Have you packed any clothes pegs and clothesline for drying wet bathing suits, etc. Also handy is a small clothes line installed in the shower. Provides a place to hang wet rain coats where they can drip.
Some campgrounds have clotheslines which I like to use when possible. I always have a supply of clothes pegs available just in case.
I would also add a small spray bottle of Awesome for cleaning just about everything. Get it at Dollar Tree.
