We were able to give this session time the green-light the evening before, just had to wait out a few clouds in the morning for there to be just enough light to begin with everyone present. This gave the family plenty of time to plan their morning routine while being able to enjoy their evening festivities and drinks if they desired. I think for some larger adult groups the evening session time *sounds* great until your family tells you there is no drinking allowed and you're not sure what time you're going to be able to eat dinner because your session time is at the mercy of the coast's unpredictable weather. 

I have rescheduled only a handful of sunrise sessions in the last two years as of the night before due to weather, and about a dozen sunsets due to rain-outs. However I can't even count the times I've had to move the starting time of a sunset session over excessive clouds or impending storms. We've even been rained ON at least three times doing a sunset session while only once during a sunrise. While it's never ideal to change your session time, we are always at the mercy of the weather and move to beat out pop-up storms and heavy cloud coverage. I ask all my families with sunset sessions to be flexible, so I encourage families NOT to make any significant plans the evening of their session as we have a good chance of having to move our time. So if you think about it that way, with a sunset session you are almost guaranteed to lose one whole evening of festivities as it will need to be completely devoted to our session.
