Need help with what to do in Charlotte NC for a 12-hour layover in January on a Saturday with a 5-year old in tow. We are open to leaving the airport, will have warm clothing eg lined jackets, a lightweight car seat accessible and just a personal item in hand each. DS loves trains, buses and all manner of things that move so bonus points if getting somewhere involves some form of public transportation. We’d love to go grab a bite and get some wiggles out for him / make it an interesting day for us. The aviation museum is now closed so unfortunately, that’s not an option. Thanks so much!
