What an awesome idea! Use solar lights in your kids rooms instead of a night light. solar lights give more than enough light at night. just place it in the window to recharge during the day and it will glow all night.
HOW TO KEEP YOUR FOOD DRY IN A COOLER. Place ice and cans at the bottom of the cooler. Place cooling racks on top of the cans. Now you have a nice dry shelf to place food in. Great idea for traveling also!
