There are numerous disadvantages: 1) Parking is easy 2) You get to feel like the only ones on the mountain (on the way up) instead of following the conga line 3) You get to catch sunrise from the summit if you move fast enough, which is awesome. The only downsides are that it can be cold, but it's cold when you start no matter what, and that you get less sleep, which hardly matters since you get so little with the normal start anyway. Extra bonus: starting at midnight means you can leave boulder at 11:00pm and not deal with lodging.
I'd also list doing a class 3 in the dark as a downside. Doing a hike this strenuous without getting any sleep before is asking for it unless you really know what you're getting into.
