I need help correcting these three sentences if possible.

[Razahia]

1.I stayed home tonight and saw a scary movie

(私は今夜うちにいる,そうして怖かった映画を見ました )

2.You and I will go to a party today and have fun

(今日あなたと私はパーティーに行くと楽しみを持っている)

3. Isn't Tomorrow a perfect day to go surfing?!

(I'm kind of stuck on this one. 明日サーフィンに行く最適な日ではないでしょう)

I am unsure what to put in between the two sentences. and I feel like there's errors all around really, I'm quite new

Thanks in advance.

Aren't there any example sentences in your textbook?

1)私は今夜うちで怖い映画を見ました。 You can leave out the ( I am in) (いる) as （で） is used to describe that your already inside the house. also the adjective scary （こわい） does not need to be in past tense (怖かった）.

2)今日あなたと私はパーティーに行く、楽しみに待っている。 Leave out （と）. Also The concept of waiting (待つ） is going to a place in time so use （に） instead of （と）.

3)明日は最適なサーフィンの日ではないでしょう。 Since your describing tomorrow's surfing day (the main subject), place the adjective before. （最適）
