我想問...

attractiveness
n.
1. 吸引力;迷惑力

attraction
1. 吸引;吸引力[U]
Detective novels used to hold a special attraction for me.
過去偵探小說對我特別有吸引力。
2. 吸引物;喜聞樂見的事物[C]
The elephants were the chief attraction at the circus.
大象是馬戲團的主要招徠力。
3. 【物】引力[U]
The attraction of the moon for the earth causes the tides.
月亮對地球的引力引起潮汐。

兩個都可以解作吸引力，　而以我所知attraction也可解作景點　

attraction 都可以解系 “景點”

-iveness 比較系講個程度。
多數形容詞都可以甘用。

preparation and preparedness
the preparation was half way done
the preparedness was not enough

attention and attentiveness
jimmy caught the attention from the class
jimmy's poor attentiveness to homework made him failed the test

"please pay attention to what i'm going to say" or "give me your attention please"
you wouldn't use "attentiveness" instead of attention.

"his attractiveness is making me crazy"
"his attraction is making me crazy?"
i wouldn't use "attraction" in the sentence.
