Flight
Springfield is a small airport and should be fairly straightforward, but rental cars may be overpriced. You may try looking into booking a rental car with Turo from a private owner, we save a lot on rentals that way. If you're booking a hotel in Springfield, there's lots of great places to eat vs. Marshfield because of the size. We would advise you to book a hotel close to highway 65 or highway 44, it will make traveling to the wedding at least 10 minutes faster.
