Answer 2

In the Dictionary.com link I gave you -- http://dictionary.reference.com/browse/fun -- it shows that "fun" can serve either as an adjective or a noun, yes.

In your sentence, I believe it's an adjective -- a predicate adjective, actually, since it is describing "dancing" from the other side of the linking verb.

To see what I mean, I'll write some other sentences which have OTHER adjectives in the predicate nominative position:

Dancing is good for you.
http://dictionary.reference.com/browse/good

Dancing is tiresome.

Dancing is healthful.
