Thanks for your input... I did ask Carnival... they assured me no DP on board
So, I will definitely carry my own with us ! As far as the luggage thing goes, it has happened in the past (on a flight) where our luggage didnt make the trip... who wants to end up somewhere with no clothes, swimsuits, etc ? I know Im being pessimistic... but force of habit ! Im sure it will end up fine in the long run... Thanks again !
