I almost never make the trip from Nashville to Vortex just to dive Vortex; Usually it also involves hitting Morrison Springs and then bouncing down to Panama City for a couple of boat dives as well.
Vortex is great if you’re looking to spend a lot of time underwater relaxing due to the shallow depths. If you’re not penetrating the cave then you’re looking ~40 feet max depth with most of it being more shallow than that so I can easily stay down 75-90 minutes on a single tank.
