The Best Western in Campellsville is a great place with electric available and good rates. So is the Holiday Inn Express. If you haggle with them a bit, you can usually get their price down some. Around back by the indoor pool, they have some electric hookups. They also have a great breakfast (as does Best Western) which is part of your room price. I've also stayed in the condos at Emeral Isle resort. They are nice, but a bit pricey. But you do get a boat slip with your rental, with electric. Parking down near the marina can be tough, especially on busy weekends.
