The airport closest to the wedding is Cincinnati/Northern Kentucky International Airport . It's a short drive to a variety of cities/areas that you'll be able to stay in. The airport has plenty of Car Rental options and shuttles to Airport Hotels.
House Or Rental
Whilst there's some great stuff going on in downtown Cincinnati, we'd suggest staying away from hotels in that area...it's likely to be expensive, you'll have to pay for parking and, most importantly, breakfast probably won't be included! If you do want to stay downtown, AirBnb will likely be the your best solution.
