Luggage porter at Venice port

We disembark in Venice. There are seven of us with lots of luggage. Some with mobility issues. I am thinking we will have the ship, nieuw amsterdam, take our luggage the night before to the terminal and am hopping there are porters there to bring the bags to a four wheeled taxi to bring us to the airport for a 1:30 flight. Is this possible or is there a better way to do this. We were looking at luggage forward but a cost of over $4000 it seemed a bit much. If we hire a private transfer are they allowed in the terminal to retrieve our luggage? Trying to avoid the ship transfer but willing to pay for assistance with our luggage.

Since you have a lot of luggage and passengers with mobility issue, I think ship transfer is easier for you.

our experiences with Venice port was that luggage porters were conspicuous by their absence-with a disabled husband would have definitely appreciated their services instead of having to drag our luggage across the spread out port area
