How long can meat stay frozen in a cooler?

We’re going camping in July for a week and a half and I’m trying to figure out whether it’s feasible to prep and freeze meat beforehand to bring with us. I’ve seen a few posts on here about freezing meat ahead of time, but most of them were shorter durations (I did see one with tips for making it last the week but I can’t find it anymore!). The campground is in a very small town and there is a grocery store but it’s very expensive and has a pretty limited selection. We can drive to another town 30 minutes away but we’re kind of hoping to just be able to hang out at the campsite until it’s time to leave.

Our cooler is just a basic igloo/coleman hard cooler and the plan was the pre-cool the night before with ice, then the day we leave put in a layer of ice blocks, then a layer of already frozen meat, maybe even have those wrapped in newspaper, another layer of ice blocks or frozen water bottles, any other meat and then a final layer of ice blocks. We have one of those thermal reflective tarps that we will wrap around the cooler while it’s in the car. If we only opened this once per day to get whatever meat we needed that day, approximately how many days could it last? Any tips or suggestions for making it last longer? We saw a ‘hack’ to make a cheap cooler even more insulated with expanding foam insulation but then I also read it’s not food safe?

I think the biggest problem with the plan is that we are taking a bit of extra time to get to the campsite - leaving on Friday and camping Friday and Saturday night before getting to our actual destination on Sunday and staying there for a week. We could change it so it’s only Saturday night but just thought it might be easier than doing an 8hr drive with a 3 year old and a 5 year old… We could also not open the meat cooler those days since I’d be okay putting two days worth of meat in a less insulated cooler. We will also have a tent trailer that has a fridge but it’s very small and we were going to try and save it for milk, eggs, etc.
