Is that 1G of constant acceleration all the way there, or 1G of acceleration until you get to the midpoint and then turn the ship around and do 1G of deceleration to come to a stop?
If it's constant acceleration the whole time, then how hard is it to stop? Can you just toss an anchor out the window as you shoot by the planet?
