What time is your reception ending??

So at the time we booked our venue we were told that we would have to be out by 10pm. In the moment I didn’t think much of it but now I’m thinking I’ll have to end my reception around 9 or 9:30 right? Is that too early? I mean I have the whole day to work with so I was thinking of doing a ceremony at 3 which is only going to be 30 minutes and then a cocktail hour from 3:30 to 4:30. So the reception could still be four and a half to five hours. I just know I don’t like when you’re having a good time and you feel like the party ended too early. We will be inviting the WP and anyone else who wants to, to go out with us afterwards to a local bar. I’m stressing over it, what’s everyone think??
