We were planning on driving down to FL but with a 4 & 1 year olds, the idea is becoming more daunting. If we were to fly, it'll just be 2 hours. If we fly, we'll probably rent a vehicle. The question is, how do we get the car seats down there? We'll be buying three seats so we'll take one on board. Car rental companies offer car seats (at least according to their websites). How did you take your car seats to Orlando?
