Would I travel for a family wedding? No question. Especially since its easy- if it were, say a qld beach wedding when df and I and our families all live in vic I would be worried about mounting cost. (Df would love a qld beach wedding )
We would book accom for the night before and possibly the night after if it were too far away from a family member willing to lend us a bed. Our boys love the thrill of staying in motels and hotels!
As for which option I think they all sound lovely. Where can you see yourself? Which would be the easiest to organise? Which will cost the least?
