Personally, I have played Raindrop Prelue by Chopin, some of the Debussy Childrens' Corner, Claire De Lune, Some of the prelude from the Claire De Lune suite (my hands weren't big enough to be able to play it properly), Traumerei, by Schumann, and if you are willing to down a grade into grade 6, Venetian boat song op. 30 no. 6 is really good as well.
I have heard played Mendelsohhns Venetian Gondola 2 in A minor Op 62. 5, and a few good Greig pieces.
