I haven't lived in the Forks for years, but you'll probably not have a problem finding a decent mid-range hotel. I recall a number of chains had set up there over the years. You may want to check one of the bigger travel sites, like Orbitz, Hotels.com, etc. for rates. But you may want to book early, since they can fill quickly depending on what's going on, such as homecoming, Gophers series, etc. As a possibly cheaper alternative to flying into GF, you may want to fly into MSP, rent a car there and drive to GF. It's all interstate, and a pretty reasonable distance for a weekend road trip.
