Greetings! This is not my first cruise, but first time taking one with all three kids (2, 4, and 11 at cruise time) I REALLY don’t want to take our car seats. If I plan correctly we won’t need them if we take the transfer from the airport to the cruise port and back. I know we don’t need them in Michigan if traveling by charter bus……so my question is “Are the Carnival transfers made by charter bus?” I just want to make sure I’m planning correctly
