I tried to make all of my "extra to burn time" by doing long cross countries in VFR conditions, like Sept/Oct, the farthest was from KLAL-KRDU with a fuel stop in between, took some friends, spend the night with family in RDU, was a BLAST.......
Do stuff like that, I don't know where you live, but take a 3-4 hour VFR flight to a major city, (you'll have your instrument so if weather gets kind crappy you can keep flying and fly around/over it), get a hotel, and goto a MLB Ballgame, or College Football Game, or something like that....make it fun, better remember no drinking!
