Bachelor/ette parties following the rehearsal dinner?

Will you all help me talk through the night before the wedding?

We live in Phoenix and are getting married in FI's hometown of LA. Our friends and family are spread throughout the country and most will be arriving Friday afternoon.

We will have our rehearsal at 4pm and the rehearsal dinner at 5pm. The dinner will have 75 of our 150 guests in attendence. We only have one person each in our bridal party, so it's mostly close family, out of town relatives we're excited to catch up with, and close friends. The dinner will likely last until 8 or 9.

Following this, we were planning to do bachelor/ette parties. He would play D&D at a whiskey bar with his good friends and I would invite my whole side of the family out for drinks to mingle and catch up. I'm worried people will come from all over and I won't get to actually talk to them at all.

However, this seems like too much. If it doesn't start until 9 it won't end until midnight and I really want to be curled up in bed asleep by then. And, the rehearsal dinner is bigger than I anticipated. Won't I have time to chat with those guests during the dinner?

But, if we nix it, we won't have an opportunity to do bachelor/ette parties and that makes me a little sad.

What do you all think? I'm feeling a bit overwhelmed.
