i have car included in hoilday but we are really stressing the car isnt gonna be big enough for cases. we are planning on taking two large cases, and one small. 2 adults 2 children plus hand lagguage.
the book states it will hold 2 large 1 small.
so we would like to up-grade, would it be cheaper to do this with travel agent or wait till we get to airport...?
