well i usually go to my dads house with her and it's a 2 hour drive. she doesn't get car sick that much (only once because i fed her before leaving the house) i would take his bed with you and lots of water. when you are at florida make sure he has all his toys and if your going outside somewhere with him for more than an hour bring water with you. if i were you i would always keep him next to you because since there will be alot of people in florida he wont be that nervous because he will be with you. i dont know if this helps....
