Just to give you some background here, I have seven kids and we have camped with all of them and the dog for two weeks. Will be out this summer with four of the kids(and dog) for 23 days towing with the minivan. What I have found very helpful is using the spreadsheet approach. I make a packing list for everyone that includes a clothing list and their own personal toiletries. For those things that can be shared (shampoo..... we bring one, or at most two (boys and girls). They can only pack what is on the list, making some leeway for things like books and so on. Basically, you only pack what you need.
In regards to food - again, use the spreadsheet. We have a meal plan for each day of the trip and we plan ahead and bring what is on the list as well as out staple condiments that we pack in appropriate sizes. Depending upon where we are going, we may pack from 3-6 days of food and will restock as needed. I'm confused on the cooler thing, because I can pack 7 days of food in an 80 qt cooler along with our small camper fridge for 9 people and we eat unbelievably well when we camp. For some folks, all of this type of upfront planning probably sounds very anal, but in reality it makes the vacation very stress free, you know what you are eating, where you are going, approx when you are doing laundry and so on. You just execute the plan and have fun.
So, my advice would be lots of pre-planning and then only bring what you need. Works very well for our clan.
