Flying with a one year old is actually easier than driving as they can get up and run around if they want to. My parents live in Ireland and so I have taken my 2 yr old to Ireland 6 times since she was born and it really isn't so bad. So if you want warm, I would fly. None of the neighboring states or short drives are to places where it is warmer. Just take a portable DVD player and some toys eg etch a sketch. Good luck.
