Times

Ours is 3:30pm-10:30pm because we get our venue until 11pm. We're just using the last 30min. to make sure everyone gets home, pack up, and break down anything as far as decorations go!

If you and your guests are more of a partying crowd, and it doesn't cost more to extend the timeline, I'd even extend it to 9-9:30pm.

That's definitely a good amount of time! I've been to weddings where the bride and groom had to extend (and pay) for additional hours because everyone was having such a good time. There have been times where the last groups of people would just take it to a nearby bar or to their hotel room to keep on partying lol.

I would just keep it to those times, and if you guys want to keep on partying you can decide then

Def. see how long you'd have the venue for! We looked at different venues and they all had different ending times on their contracts/packages. We really liked how ours ended at 11pm because we felt like we'd get our money's worth, especially since we'll have it from 9am-11pm for no extra charge.

I think that's enough time but it's also early enough where you could continue partying elsewhere
