Why is Kit disappointed by Wethersfield?

From the text:

Her heart sank. This was Wethersfield! Just a narrow sandy stretch of shoreline, a few piles sunk in the river with rough planking for a platform. Out of the mist jutted a row of cavernous wooden structures that must be warehouses, and beyond that the dense, dripping green of fields and woods. No town, not a house, only a few men and boys and two yapping dogs who had come to meet the boat.
