I sure hope that when you say you are wanting to visit the Smokey's, you mean the Park instead of the tourist traps of Pigeon Forge and Gburg.
Stop at the Visitors Center. View the displays, watch the movie, then drive up to Newfound Gap. Pack a lunch.
Plan on a early rise and drive the Little River Road over to the Y and then on to Cades Cove. Plan on a hike to Abrams Falls. about 5 miles RT. Several old homesteads and churches along the Cades Cove loop. about 11 miles. If time permits hike up to Laurel Falls on the way back. The trail and parking can be crowded. Pack a lunch and take water.
Plan a early start and drive the Roaring Fork Motor. Along the way, you come to the trail head for Rainbow Falls. At 80 feet, it is the tallest clear fall in the Park.
Drive back up the Newfound Road to the trail head for the Chimney Tops. This trail will take you to some views of the mtn's and the great fire.
OK....Now you can do some of the touristy things.
