Question about puppy's last vaccination

So Golem's last set of shots is tomorrow morning, and we are all very excited since now we can start introducing him to the big world outside our backyard My mom is having a small family party at her house on Sunday and now that he's fully vaccinated, were hoping to bring Golem with us instead of having to stay home again. If his shot is on Friday morning, is this enough time for the vaccination to go through his system? We've been very strict about our vet's recommendations, and I don't want to put him in any danger now after all this time of being so careful. But, I'm thinking that 2 days after his last shot would be okay to bring him with us to Mom's, right? Or am I just being an overly-concerned first-time puppy-mom again?
My mom just has a cat, but it's an indoor cat who is fully vaccinated and sees the vet regularly. We'll be at the vet tomorrwo to ask, but the suspense is killing me so I just want to get some opinions here first Thanks everyone!!

Thanks Shana!
And you're right about the sleepiness. Craig has taken Golem for his last few shots, and he says when they get home, he sleeps for hours! He's still such a baby yet, even though he acts like a little monster sometimes! I'll have to post our pics of him from Christmas soon - i keep forgetting!

he'll be inside unless it's potty time, so I think we should be okay too. Just wanted to be sure though Thanks!

How come my dog gets her shots and comes home bonkers... she never is sleepy never never never
