Stephanie, it is soo good to hear from you, sweetie! I'm happy to know you found a way to help your family through your FIL's passing. I know that was hard on you guys. Funny how your son count's "sleeps" to events. That's what Adrian does. Amazing how kids find to turn things into a form they can understand.
Sounds like you have an amazing trip planned. Are you going to keep a travel journal? A paper bag album would be great for this as it would provide pockets for tucking in things like travel stubs and other mementos you'll pick up along the way.
