Writus Interruptus

Thank you Dr. Cavanaugh for facilitating these monthly therapy sessions just for writers.  If you're a writer and you're insecure---a redundancy if I've ever heard one---join the club!
 
Here's my sad, sad story for October:  these last couple of months I've been making great progress on my current WIP.  I estimate I'm two-thirds of the way through the first draft at a current count 57,000+ words.  I know it'll need lots of polish and some reworking when I get to draft two, but I'm pleased with how it's coming along.  I'm in a groove.  And tomorrow . . . I leave on vacation.

More accurately, it's a quest for fun.  That's right, three generations of blood and in-laws---nineteen of us in all---are gathering at the real life Wally World for what certainly won't be relaxing, but most definitely will be fun. :)  The thing is, with my focus interrupted for seven whole days, not to mention readjustment time once we return home, will I lose my mojo?

It took me over a year to recover from the first book being published before I revved up the whatever-it's-called to go at this next manuscript in earnest.  (See?  I'm already losing my ability to summon a fitting noun on command!)  Will this trip of the century---during which there will be no time to scribble anything on a notepad---throw me into another tailspin from which it'll take me far too long to recover?  

Tell me, what do you do to rekindle the magic when your writus has been interrupted?
