I noticed that you said that you don't care for KOAs, but I'll pass this on anyway. We travel across I-10 on a somewhat regular basis, and have stayed at the KOA at exit 10 on I-12 just east of Baton Rouge on several occasions, and found it to be convenient to the highway, and nicely kept. Each of our stays was only one night, so we can't really comment on the amenities.
