I only shoot beach portraits an hour before sunset. The last few minutes before sunset are obviously the best. So...if my clients have really small children that might not last an hour - I push it back even more and start about 30-40 minutes before.
Exactly what Jill said.... Around here the sun doesn't set until 9:30 or 10:00 in the summer. When I tell parents of little kids that we have to do them at 8:30 or 9:00, they freak out and say that it is too late for thier young children. I tell them they are welcome to wait until October when the sun sets earlier...
There have been a few times where I caved to the parents pressure of going earlier to the beach for the kids. Every time I did, I regreted it. The light is too harsh.
Now, when doing a wedding, you don't have a lot of choice on time. So, just go with it, and do the best you can. I will try the sun both at their backs and on theri faces. If you shoot with the sun at your back, they sky looks bluer than if it is at thier back. If you shoot with the sun at thier back, there is nicer light on thier faces.
I just went to a beach photography class, and he used a lot of scrims for the shots of the bride and groom models. Of course you can't do that with the wedding party.
Oh, and one more thing... if it is very overcast, the last hour can be too dark. The clouds almost act like a horizon, and it is like the sun sets earlier. I usually try to warn my customers that if that happens, I will call them to go earlier to the beach.
