Is this homework?
I'm confused by the sentence as written. Which option is acceptable?
Having a wedding in the air _______________ than having one at the hotel.
(A) is more fun (B) is funner
It's a question.
Having a wedding in the air is funnier than having one at the hotel.
That is not an option, and means something different. 'Funnier' is not the comparative form of 'fun'.
From the forum guidelines:

I am not a teacher.
Fun is primarily a mass noun.
We can use it after the verb "to be" to say that something or someone is fun.
Fun as an adjective is already informal and although you might hear "funner" it is very informal.
I don't consider it a real word and my advice would be to avoid using it if you want to sound like you know how to speak English.
Native speakers that know better can get away with using unorthodox language for effect, but until a learner is completely at ease with English idiom this sort of thing is best left alone.
Having a wedding in the air is more fun than having one in a vacuum.
