There are several different ways to approach this - I dunno if you want help from a novelist who has never been able to finish a book at hand yet without having major writers block about 200 pages in but I will give you some stuff to think about.
A) Does there NEED to be info about the trip between the inn and the city? Is it a good place to maybe either have a chapter break or split the book into Part One and Part Two? Easy way to get past a boring part of the book.
B) What might seem uninteresting while you are writing it could in fact make or break the story in the long run. Is it a time to get to know the character? Maybe its a time to introduce some other characters into the story?
C) What could possibly happen in this fantasy novel on the way to the city? ( I would give you ideas but this is your book and unless you are willing to give me a cut of the profits HA HA HA you need to create it on your own - you will feel better about it when you are finished if it is your own)
D) Have you been writing straight for a while? Taking any breaks away, even half a day or so? Distancing yourself from a troublesome spot while writing can help. Or just try playing some music (i loooove music when I am writing, not many do) or taking yourself to a place you find inspiring and try writing once you are there.
Just some random thoughts. Hope it helps.
