traveling with a baby

Jacqueline
So we live in Michigan and plan on visiting my parents who are in Florida come March. My LO will be around 8 months. 
I can't decide if I want to drive or fly. 
Driving I feel like would be so much easier with bringing everything (stroller, carrier, pack and play, bags) however it would take longer then the estimated 22 hours. With stops and everything 
Flying I'm stressing about because of all the items you bring I feel like it would cost a whole lot and then I'm freaked that baby will have a total melt down. 
Any tips on what to do would be greatly appreciated!
