If there was one scene you could add?

I would like to add the scene in the Shire where they meet Gildor and the Elves so Sam would have his moment of discovering the Elves. Also, I would like to see them arriving at the 3 stone trolls and making the connection to Bilbo's story. In Lothlorien, I would love to keep the moment where Frodo discerns Nenya on Galadriel's finger. I agree with the others who said that Sam's job as gardener should be made clear, and also would like to see Bilbo at the Council of Elrond.
