We'll be staying on property and normally take the buses to the parks. Our next trip will include a 16 month old. Do we have to bring a car seat on the buses? How does that work? I have read for the Magic Express you do (but I could be making that up, sleep is a luxury) but what about from the resorts to park? I know we have the option of taking our personal vehicle but I'm not sure if we will or not (we'll play it by ear and see how baby is behaving at that time and how we're feeling).
