My Little Union Pacific: Big Boys are Magic

I was thinking since Christmas is right around the bend, I was thinking of doing a Christmas fic of me going to a Christmas Market in Germany with Princess Cadence. I am basing this of a MLP birthday game which deals with world travel, I was born on December 12th. I got a basic concept but I would like your opinion on this topic: would like the character to be regressed to younger age (5 at the least, probably 10 at the most) or just stay as a 16 year old teenager? Tell me what you guys think.:pinkiehappy:

I know this is short notice but I figured it would be appropriate for this time of year. There will probably be two versions of this story one with the character being regressed to a five year old and one where the character will remain a teenager. This will probably be a four chapter story. I will also work some more on the next chapter for this story as well. Probably might rewrite the chapter where the ponies discover the Iron Monsters we all know and love and add their reactions to the steel giants and add the original characters I asked to borrow. I am doing this for you guys because I love you.:raritywink: But I could use some help with Verbolten Speed Demons of Equestria as well (this story took over the spotlight:twilightblush:) I hope everyone has a wonderful night and remember tomorrow is Christmas Eve.
