I think you will thank yourself in the end for this "goof"!!
Ghent is just such a cool place (as is Bruges). Brussels is a cosmopolitan big city but I think you'll get more of a feel for Belgium and the Flemish culture with some time in Ghent.
IF you are looking for a Ghent hotel, many of us have stayed at Hotel Harmony. It's where most of the Rick Steves tour groups stay and it's in a great location on a canal. I usually take a taxi from the station but it's accessible via the tram system. You KNOW any place that has chocolates and prosecco on the breakfast buffet is awesome, hahahaha!
DO look at getting timed entries for the Ghent Altarpiece at Saint Bavo's Cathedral. Get the Augmented Reality tickets to get the history of the artists, the Van Eyck brothers and the development of the altarpiece.
