Wedding Timeline - is this okay?

Hey ladies -


Trying to set our wedding timeline and this has honestly been one of the hardest things I’ve had to do for the wedding, lol. I can’t seem to decide if I want to have the ceremony at 3pm or 4pm. We have the venue all day until 11pm and sunset is at 7:30pm. How long is too long? Here’s what I keep thinking?

4pm - arrival time listed on invitations4:15pm - start ceremony 4:30pm- ceremony concludes 4:30pm-5:30pm - cocktail hour/wedding pics5:30pm- dinner starts 6pm - toasts 6:15pm - first dance/mother/son dance6:30pm - desserts and floor is open for dancing 11pm - everyone leaves

4.5 hours too long for the dancing part? We have games and such for every one to play.
Should I start it at 5pm instead?
