Dufus

Why not? Nami wants to draw the map of the whole world, laugh tale is said to be the last island. Nami needs to visit every island to draw its map to complete her dream. (She wants to personally experience the places and draw their maps)

It's sanji whose dream doesn't seem all that connected. He wants to find All blue. We don't know if all blue can be found at or around laugh tale. If they found it before reaching laugh tale then his dream is basically completed before reaching the last island.
