I really need some advice please.

I am picking up a French bull dog puppy a few days before Christmas. The day after I pick her up, I have to go to family's house for a family meal, which is about 90 minutes away. I can't skip it, as one of the family members we only see once every few years has come over this year.

I was going to bring the puppy with us for the day to our families house. We have a pet carrier we can travel with. OR she could sit on a family member's lap in the of the car to feel more comfortable, as we wouldn't of had time to do crate training.

I did request to pick her up a week later and the breader said she can't hold her for me for that long, as someone else will probably purchase her by then.

Is it a bad idea to take a puppy I have just purchased to see family?

Thank you, any advice would be greatly appreciated, as this would be our first pet.
