Gonzo-to me there are many questions to be answered before I could give advice to you on camping with family members that don't contribute to a group vacation. Do you LIKE camping with your family? Do you feel crowded when they are along or not? Can you afford to take them camping? Is your family close and, when needed, do you all help each other out?
Except for our children/grandchildren, no one in my family wants to come camping with us-the thought of camping is not a pleasing thought to them. When any of our children or their families come with us, we are lucky enough to be able to afford to foot the bill. We have a fun time.
