planning on heading out on xmas day with family of 4 (kids are 2 and 5) and a dog. Budget is 750 dollars (Cdn) or around 620 american for one way due south. how far do you think the peters' family will get? we will also reward ourselves with a 300.00 day or two once we hit 750 dollars (cdn) and then will header due north on I-5, (with our 750 return funds)back to van. i'm hoping we can make it to someplace warm near a beach.
