How to set a wedding time

I am trying to plan all the times out for our ceremony and reception which are 30 min apart from each other. The sun sets at 5:30 (keeping pictures in mind) and we are having a first look. The ceremony space gives me a 4 hour time frame. I thought of booking 2:30-6:30, take pics at 4:30 and the ceremony at 5:30. They suggested this time frame in order to pack up our belongings after a 30 min ceremony. Then, cocktail hour from 6:30-7:30 and the reception from 7:30-11:30. I was told this might be too late. Im trying to think of what would be best when considering golden hour for pics, an appropriate time for the ceremony, the reception and drive time. Any advice or suggestions would be greatly appreciated! Thank you so much in advance!
