A young family road trip in the heat: one hatch bag, a snack daypack, and a plan for wet swimsuits.
A beach week with kids is the young family road trip, hot, for seven days. The car seat stays installed. The hatch holds one expandable clothes bag. The daypack holds snacks, a bottle, and the shirt you will need before you get back to the rental.
This week is the hot road trip. The young family travel journeys keep the same seat-first order for flights, rail, a cruise, and a trail day.
The picks below are gear already filed on the A family road trip, hatch to trailhead journey. Each line says why we picked it for this trip.
Keep the 45 L expanded as the dresser. Cubes come in; the bag stays in the room or hatch.
Two bottles and a wet cube. That is the spill plan.

No. One 45 L bag in the hatch plus a daypack for snacks covers the week if you wash once. A second 45 L pack is how the hatch fills with duplicate clothes.
The spare shirt, snacks, wipes, the 24 oz bottle, and the hat. Leave the 45 L in the rental or the car.
In an Isolate cube, away from the dry stack. That is the wet-clothes job on this road trip.
