I'll go wake up Beth

[Topstudent]

I'm trying to write a script:

MOM is making breakfast. DAD is setting the table.

MOM: Breakfast is ready in two minutes.

DAD: Okay. I'll go wake Beth. / I'll go wake up Beth. / I'll go wake Beth up. / I'll go up and wake Beth. / I'll go up and wake up Beth. / I'll go up and wake Beth up.

Which one of these is more natural to you if Beth, their daughter, is sleeping in her room upstairs?

 

[Barque]

I'll go wake Beth.

I'll go wake Beth up.

I'll go up and wake Beth.

These three, the first for choice.

Most natural in BrE: "I'll go and wake Beth up".

 

[Skrej]

I'll go wake Beth.
I'll go wake up Beth.
I'll go wake Beth up.
I'll go up and wake Beth.
I'll go up and wake up Beth.
I'll go up and wake Beth up.

The first four are all possible. The last two are grammatical, but unnatural with the repetition of 'up'.

I'd personally use either the second or third.
