Need help starting the next chapter.

So after a hectic week of sharing my space with my nephews, I've finally got it all to myself. Now that thats out of the way, I need some help.

So August 13th I posted that the next chapter would be A Trip to Canterlot and that it would be about just that. Comet will meet Celestia and Twilight. However I'm having trouble deciding how to start off. I've got scenes of the Apple Family getting ready, The Train ride to Canterlot and Comet sharing his anxieties about the trip with his family.

So the question I'm asking is what do think should stay and what do you think I should cut as filler? Before you answer I'd advise re-reading Chapter Ten The Apple Family Way since I recently rewrote the ending to fit the new narrative after deleting A Royal Visit. So read that first then comment on what you thinks most important to the plot and what can be cut.
