I don't set up until Halloween day and would suggest doing a trial run if you can for placement and for any cords and lighting you will be using. Definitely want to test the lighting to make sure it works. If you are depending on sensors to activate your props, test these with your placement as well. If they need a light beam to be broken and that doesn't happen, you'll be disappointed. Test everything out as it gets darker. Takes photos in the daylight and at night. If you can set up on Friday (with Halloween on Saturday), you could mark your driveway with chalk for positioning for a quicker reset the next day (already knowing where everything should be positioned, and hopefully you can take it down and store easily in your garage until Saturday.
We're doing a mad lab this year and I'm hoping to start temporarily staging the larger items on our porch and courtyard to see what will fit and where. Right now I'm not sure I can fit in the two John Doe lab tables the way I'm hoping and still allow enough walkway for the kids. In your case you might find that you'd be better off with fewer props out or staged differently.
Hope you'll come back and post a photo from your big night. I've seen some very well done driveway set ups here on HF over the years. Wish I could remember who did one in the SF East Bay so I could link to their photos for you. A search for "driveway haunt" will turn up photos and tips.
