A nightlight or two
Countertop ice maker
Small collapsible tables for sitting around the campfire
Tablecloths - either cloth or disposable to cover the disgusting table at the campsite
A table to sit next to your camper for the ice maker, etc.
Portable water container
Beverages, whether they are "adult" or not
Lots of paper towels and disposable everything - paper plates & bowls, cups, plastic utensils, etc.
I could just go on and on, but I don't want to scare you! I don't like to be without anything.
