I prefer not to go out tonite/not going out tonite

I prefer not to go out tonite/not going out tonite
 

Are both correct or just the first one?

Both are correct except that the spelling of tonight almost made me ignore your question. :D

OPs, I thought it was a high-leveled register of tonight :D :D

I think I'd prefer would be better.

I agree. It is more common to use "I would prefer...." in this scenario.

Hang on - the question was whether the sentences were grammatically correct, which they are. The "I would prefer...." is also correct, but is a different situation, and we don't know what that is.

Oddly, I have just used the sentence myself. There is an issue whether we go to some function on Saturday night. My wife is going, and I am not, and I just explained to friend that 'I prefer not to go out that night'

:)

I don't understand tonite means tonight in that phrase.

Thank you for your explanation

This is just a spelling difference between BrE and AmE. It means exactly the same. :)

I understood everything now.

Thank you for your advice.

You making a moutain out of a molehill. HAHAHHA
