You sure you want to go through the hassle of driving? I'm sure it'll be a fun road trip but really, it won't save much cash. I'm currently looking at ~$250 round trip all in for flights and I'd rather chill and watch a movie for an hour and a half but that's just me.
My current plan, pending spousal approval, is to fly out early/mid-day Friday and back as late as I can Sunday.
