Mahoney State Park is about 30 minutes from both Omaha and Lincoln. If you're flying from out of state, we recommend flying in through Eppley Airfield (OMA)--there are many more airlines and flights available!
In terms of hotels, there are dozens of viable options in Omaha and in Lincoln! The Lodge at Mahoney will be undergoing room renovations during our wedding, so renting a room there will not be an option in June.
