Experiences on Limo Drop off/ Pick up at NO port

I posted this in gulf coast departures too and really need info:

Hello All,

We will be traveling about an hour away from NO and it will be a party of 8 for our Nov. 2012 cruise. We are debating on renting a very large van to drive & park @ the port or hiring a limo service to drop us off & pick us back up. Surprisingly, the large van rental is only about $100.00 cheaper, (including port parking) assuming we won't get charged the extremely large vehicle parking at the port, from the limo round trip service! To me it's a no brainer, I would choose the limo round trip service to prevent from driving from and back home & since it is a small difference $$$ wise and less hassle. My only question is if anyone has had any problems getting dropped off/picked up by limo at the NO port? If not, please tell your good experiences with drop off/pick up Limo services at this port. Thanks.
