Goodness, someone finally replied.  The good news is we don't have to go down a day early, we can go down the day of surgery.  Surgery is an "afternoon" slot, we won't have any more info until two days before. 
Here's what goes through the head of a medical mama when she hears afternoon surgery:

Pros: Yay, don't have to go down the night before! Saves $50, a night of poor sleep and one time of setting up and tearing down all his equipment.  (About 20+ minutes up, and 20 down).  We'll still bring everything in case we have to stay in a hotel for any length of time. 

Cons:  Very hungry child to distract.  Early AM surgeries they sleep through most of the hunger.  For example, (this is vaguely, haven't done that math yet)... 2pm surgery means (3pm surgery, lol)..  no "food" after 6am, no clear liquids after 10am. (yay for a tubie that can eat overnight!) That's a long drive down w/ a hungry child!  We might have to do drive through and stop somewhere to play so he doesn't beg for the random food we can give him.  Other big con, surgery never runs on time.  "on time" is a half hour late, normally they're an hour to an hour and a half behind.  Which means, for a 2pm surgery, you have to be there at 12:30, and are in a 8x8 foot room from 12:30-3:00.  That's when you pray for an opportunity for a long, uninterrupted nap (ha, ha, right!?)

And, because i'm lazy... this is copied from FB:
 Hotel booked... and even the one closest to the hospital (and cheapest) because we're seeing a doc from University Hospital, we can (hopefully) stay at the hotel for UC patients.

That saves us about $15 per night, and the cost and hassle of driving 15-20 minutes to and from the hospital (which... means i'll actually leave the hospital!)  This "hospital hotel" is a few minutes walk that's safe enough during the day i can go by myself.  We're sending in our info to the Ronald McDonald House.  Even though it's a longshot, we're going to try in case we end up there for 5+ days.  That would save us about $15 more per night, plus almost all food costs (it adds up fast!).  The last 2 big surgeries we spent 8 days in the hospital, and 3-4 at the RMH.  We are hoping for less this time! We've learned a lot since then that should get us out sooner!

So, there's a peek into the logistics of the day of surgery.  Don't be jealous, now :)
