Depending on wait times, the boat might be a bit quicker, if time is an issue. It's a little bit of a hike from the Contemp boat dock to the monorail (always longer than I remember it being)
But then again.... it's also a bit of a hike from the boat dock at GF to the restaurant too.
Hmm... the more I think about it, the more it might be 6 of one, half dozen of the other.
