How many suitcases does it take to go 2 hours north for 3 days?

How many suitcases does it take to go 2 hours north for 3 days? Ugh.
I just finished packing for us to go up north to the In-Law's cabin for the weekend.
One big suitcase for mommy & daddy.
One small suitcase for Shaun.
One duffle bag for Ainsley.
One backpack for activities.
One mini-dvd player and movies for car ride.
One nebulizer and medicine for breathing treatments.
2 blankies and snugglys (stuffed animals).
2 kids bikes & helments.
Baseballs/Bat/Mitt.
3 Quad helmets.
Chicken nuggets for kiddies, drinks without aritifical sweetner for daddy, pretzels for poppy, animal crackers, paper plates, wheat thins....etc..
Sippy cups, pull ups
I'm tired already - maybe I'll stay home (will they notice I'm not there once it is all packed in the truck?)
