Or get a music theory book to study during down time. Thisis a good one, at least I thought it was.

If it's a driving vacation I advise against reading it while driving. Otherwise, you'll find later in your studies you wish you knew more theory and knew the fretboard better, etc. You will be getting ahead of the curve.

Most importantly, enjoy the vacation.
