Head to the GSMNP, Sevierville, TN. There are thousands of golf carts, especially at River Plantation and it is on a river instead of a lake. You can get the river front sites.
There are many seasonals there and they all have golf carts. Many of them are orange/white with big Ts on them, but you can stand them for a few days!! hahaha
You are within an hours drive of some absolutely breathtaking views in the GSMNP with waterfalls, great hikes (some even handicap accessible), lots of shopping, music, Dollywood, and about anything else you could possibly want.
Mapquest says it's 8 hrs and 17 minutes away.
