Best transport option for 10 in NOLA?

There will be 10 people in out traveling party. Our flight arrives after 11 pm and we'll need to get to our hotel Courtyard By Marriott New Orleans Downtown/convention Center. Is taxis are best option? Would a limo be reasonable?

I would just suggest taxis.... probably the fastest & easiest option. We tried to arrange a limo transfer for a group of 7 last February (to the same hotel you're heading to :) ), and couldn't make it work because of the amount of luggage. We were able to fit in one 8 passenger van taxi... but you'll probably need 2 vehicles.
