Is this an unreasonable photography timeline?

2pm - final stages of getting ready shots, both boys and girls on the same property 3pm - ceremony, no group shots or congrats afterwards, 3.30pm - straight into family shots (14 people all up, 2 families) the property then a few bridal party shots at same location as family shots, 4.10pm - Bridal party and bride & groom shots off property (5 min drive) 5.30pm - Bridal party re-entrance going into reception, 6.20pm - Sparkler shot 6.30pm - Dinner 8pm - Cake cut and first dance
