We sleep in almost every day, so I voted "always", though we do get up a little earlier if we are going to Busch Gardens in Tampa or something like that.
Otherwise, we get up when we wake up without an alarm...usually about 8:00 a.m. Our teenagers, on the other hand, tend to get up around 9:00 - 10:00. That gives DW and I a chance for a morning walk or a workout.
