I-95 is difficult to get lost on, though around Washington DC it can be congested - especially during rush hour. Granted, I've experienced this coming from Virginia, so your experience may differ heading South.

I would heartily recommend getting out there on that bike and enjoying the warmth of Florida while those of us up North are still wondering when Spring will arrive. If you stick with camping on those trips away from your relatives, you should be able to make the trip quite affordable, too.
