As a performer, everything with the Prince's Ball, but especially the footbridge because of the wide variety of emotion I get to portray as an actress. Even though the anxiety, stress and fear of the actual situation were just that.
Watching, a lot of the scenes between Percy and his men. Creation of Man especially is all around fun to watch, and it seems the audience agrees as we've had a few people stand up at the end even though it's before the end of even the first act.
Song would be a tie between When I Look at You and The Riddle. While again the situations and emotions were horrid to deal with in the Dreams, musically I really enjoy singing them.
The one thing I actively dislike is the portrayal of St.Cyr, but as it's only those few months of time, it's not like they will show him for the man I knew in the dreams so I just have to accept it.
