Sneak in.

A long line like this isn't something you can wait in. You need all the time you can get, considering you need to secure a place to sleep. Taking in the large, stone gray walls of the city, you make out two potential way to pass in, without the need to wait in the line.

One, A small grate that lets out a small stream of muddled water into a small stream that flows outward, into the field.

The second, is a more... lewd, idea. One of the guards has gone left, seemingly relieving his bladder on some poor grass on the side of the walls. Gerthum did say that i should think of this world as a play box of sorts, in terms of sexual occurrences. Perhaps you can convince him to let you skip the wait?
