Try it a few times at low speeds on a deserted road to get the feel for it.

Ah, the dreaded "Tranny-Bomb" -- although in partial form (full throttle N-to-D shifts at speed will grenade an automatic after a few times). It's safer to be under the RPM engagement point, in most cases, than over.
Something that hasn't been brought up. Engine-off coast (EOC).
(By all means, if you're considering it: practice, practice, practice -- without traffic or obstacles).
It hasn't been 100% confirmed that it reduces transmission life, but Honda transmissions
generally aren't rated for towing with the drive wheels in motion.
I started EOC'ing about 30-40K miles ago (2 or so years). I also tightened the throttle cable for firmer shifts (less slippage), and should be 1/4 of the way through changing out to a near-full synthetic fluid. EOC increased my FE quite a bit. As the vehicle ages, I am backing-off of this procedure. Instead, I've replaced it with lower top speeds and downshifting for DFCO (who knows if that's wearing anything out -- probably). The shifter is a busy place these days.
I assume your car has that darned "Hill-Logic Control" to gear-hold up hills or down steep ones. EOC will confuse the daylights out of the TCU's calculations, and TC lockup may be significantly delayed (especially if EOC'd at high speeds).
Armed with that info, if you want to play it conservatively, neutral coast with a rev match (if you do it just right, over 35 MPH, it should be unnoticeable followed by a little shift with the TC engagement). Shutting off at lights/etc and back to drive shouldn't be that big of a deal.
