Thanks everyone for the replies the other day and night!
My timings have changed but the format is staying the same.
so, to make better use of the light the timings are as follows;
12 ceremony
12.30- 2 photos etc
2-5.30 - wedding breakfast/speeches/cake cutting
6 evening starts
7.00 first dance
8.30 buffet
11pm end
not as imaginative as I wanted, at all, but the oh wouldn't budge
