Sounds like a solid plan for the kids next week, and yes, they will all love a their one on one with Dad.
Follow your gut on this. If you have doubts about showing up right away, just wait a bit. I know you will be tempted to go the house first thing, but you should probably get some rest and head over later in the morning. I know you miss your children, and this would be my first instinct too. If you wait, you will be a more clearheaded CVA and better be able to deal with your W in a productive way. I know right off a red eye I am nearly incoherent and would not be thinking clearly. Don't want to have a backslide due to exhaustion.
