Hi Allevart! That sounds like soooo much of a good deal, I think I hate you already! [Just kidding, really ]
When you're doing your planning though, just remember the old saying - if you want to get somewhere, fly; if you have to get somewhere, drive. So if you have day out-and-back trips that could be done either way, go for it, but if you have to travel to a string of places and you absolutely must be at each one on the designated day, then I'm not so sure...
Then again, you used to fly so you already know that.
