Too soon to leave pup with sitter?

We’re looking at getting a toy poodle as first time dog owners. I have two different breeders to visit over the next few days.

The older puppy that we will see will be home with us at 9 weeks on the 17th. We have a fixed plan on the evening of the 29th, is this too soon to have a puppy sitter come for the evening? We would hopefully have just got the pup fully vaccinated. It wouldn’t be a sitter that I know, but rather a professional. I would arrange for them to be introduced ahead of the evening.

This situation isn’t an issue for the second puppy who is younger and would be collected after the 29th.

My other thoughts is that over Christmas we will be staying with family with the puppy. This would mean bringing it to at least 2 new houses with new people (no children though). I thought if we bring its crate and all its things and probably have the crate in my room that might be ok? Or is this confusing? I want the puppy to grow up to be really well socialized and able to be in all sorts of new environments.

I’d like to get a puppy ahead of Christmas as I have time off for nearly 2 weeks. If I waited until after Christmas I wouldn’t have that long.
