okay so we're checking on rooms for the night before our cruise and we're probably going to use the park and cruise shuttle thing and i just started wondering what to do about our baby? he's 18 months old. um do they even let you on the shuttle without a car seat? are there seatbelts on the shuttle? is it possible to take a car seat and then have the shuttle driver drop it back off for you at the hotel (FOR A LARGE TIP)?
