Thanks for your input guys! We actually don't have plans for our final day and night, so location really won't matter to us much. We were at the World for a week last September and were very planned out, and did alot of time inside the parks, so we're heading back to enjoy some time in the parks, but a lot of time relaxing, pool side, in restaurants, and enjoying beverages. We don't have children, so that's not too much of a concern.
We always try to hit one big blowout meal the final night, and did Yachtsman and Morrimotos in September, and have eaten at Le Cellier in years prior.
I was leaning towards Narcoossees or the Boathouse, but it sounds like Narcoossees is a real winner!
