Vacation Rentals: We would recommend staying at one of the many airbnbs in either Darby or Hamilton as these can be really fun, ranging from riverfront cabins to farm houses. The 4th of July weekend will be a popular one, so you should book early if possible. Our friend Lindsey has 3 large newly built barndominiums with multiple 1-2 bedroom units in each building, located about 10 minutes from the wedding venue and 5 minutes into the town of Hamilton.
Motels: There are also several budget motels in the area, definitely nothing fancy. The town of Hamilton is slightly bigger than Darby and provides more shops and stores.
