DS is 11 and still has an occasional accident. We restrict his fluids in the evening, and we get him up at 1am as well. He is a very deep sleeper, and when we wake him up in the night, he isn't fully awake. He has said some funny things, and he never remembers getting up. He sleeps through the loudest thunderstorms.
He doesn't like to wear "diapers" (goodnights) but we have some he uses when he spends the night at his grandparents house. He has slept over at his best friends once or twice and he has taken the goodnight.
