Car seats. I am going to do my best with my info so please forgive me if i don't have everything yet. So we fly in the day before and getting picked up at the airport by our hotel (non-disney, don't know the name) then the next day getting picked up by disney and being taken to the ship. We have a 4 year old and 19month old, do we need to bring car seats for the shuttle rides or will they have them? And of course the ride back to the airport after the cruise.
