It works fine so long as your bedtime isn't 9PM 😉
When I took it, we were done by 10 or so. I liked it because I got to sleep in, get a leisurely breakfast, relax a bit, and go into the exam fresh, rather than waiting for my coffee to hopefully kick in before my first case. I suppose the downside is that you obligate yourself to stay in a hotel for 2 nights, rather than being able to fly out after the exam (I suppose you could fly in the morning of the exam, but if your flight is delayed for some reason, you'd be totally screwed). I didn't have any problems with it in terms of energy, since once you get going, things are just flying. I honestly hated having to take that first break, since I had a good groove going by then.
