I agree, FireyNurse! With our group I dont think we need pictures still going at the very end of the reception.
After considering it all I think we are going with the 5 hour package.
Here is what I picture:
@ 4 : Juan arrives to start take pictures of the wedding party getting ready
5:30 - 6 : Ceremony
6 - 7 : Cocktail Hour and time for group pictures and sunset shots
7 - 9 : Reception photos
