I'd like to fly my son over to the museum sometime, and am looking for "last few miles" transport suggestions. Best I can tell, Signature is gonna charge a $49 ramp fee at Huntsville International, which makes me cringe. From there, it is either a 10 mile uber ride or a car rental to the museum and back. Decatur (DCU) won't have the ramp fee, but it's 20 miles away from the museum, which would almost certainly require a rental. Suggestions?
