My husband and I are thinking about making a trip down to Disney World in November. We usually drive down and have decided that maybe we would fly down instead. Has anyone flown to Florida with a two year old? If so did you take your car seat or just let him sit in one of the seats without it? The car seats that we have are too big to fit in one of the seats on the plane. At least according to the measurements on the website. Is it worth buying a new one for the trip or borrowing one from a friend? Any information anyone can tell me would be appreciated. Thanks in advance!
