I was expecting armageddon, but it was the easiest thing ever. It wasn't until a few weeks or maybe a month later that he started objecting a little. When he does, he waits until we've left the room and then he gets up and comes running down the hall giggling
A couple weeks of silently but emphatically putting him back to bed solved that.
I also found that it became even more important to make sure that he's READY to go to bed. He does the running down the hall thing now when he's just not quite ready yet, not so much as a game.
