I have no idea about Fultons, but we loved Artist Point so much on our recent trip that we canceled another restaurants ADR so we could come back a 2nd time. I'll have reviews up for both of our visits in the next week or two on my dining review thread (link in signature).
Been to both, and love both of them.
If you go to AP, you can walk around this beautiful resort, and time it with the Water Parade and watch it from the beach at the WL.
If you go to Fulton's, you can walk around DTD - which has lots of shops and restaurants.
Depends on how you want to spend your evening. Tough choice, good luck
