Only one suitcase?!

We are headed on our first official vacation as a family of four.  We've been planning our trip cross country to see my sister for the past 5 months and it is finally here!  We booked the flight, secured our accommodations, but what comes next is just exhausting....PACKING!

Due to flight restrictions, we are only allowed one suitcase per person.  So we're fine, right?  Uh, NO!  Let's face it, I'm a woman and I LOVE shoes!  That means that one of my son's checked bags will be the best part of my outfits and the two boys will share a suitcase.  Under normal circumstances, this would be fine, but the ever changing climate of California has us packing for two very different temperatures.  So how do I fit it all in (and not wrinkle it all)?

My very wise mother once told me that when packing, I should do the following:
1)  mix and match my clothes
2)  use dry cleaning bags in order to reduce wrinkling
3)  roll my clothes to save space

I've kept the dressier clothes (dress shirts, dresses, etc,) in the dry cleaning bags that they came home in.  The bags keep the clothes from wrinkling even while folded in the suitcase.  I rolled my cotton clothing  into a tube shape.  This helped with the space issue of the clothing...it also helps with less creases when other items are on top of it.

Now if only I could find a way to fit all my shoes in!
