i'm such a night owl! in fact, i'm the only one up at my house right now...and will be for another hour or two....but that's beside the point. anyway, imo, E-nights is definately better! more people (especially families with youngsters) tend to get up early rather than stay all day at a park and then stay up even later...most of the time after a long day, people just want to get back to their hotel....therefore, there are less people in the parks during e-nights as apposed to early entry....besides, disney world just seems to come alive at night! but what the hey! i say take advantage of both if you can!
