We are leaving from NO Dec. 18th. I have not been there personally, however my inlaws own a timeshare there and have assured me we are staying in the right spot.
We booked at the Doubletree on Canal street, which is near the Julia Street cruise port. It is about 2 blocks (if that) from the cruise dock, so we may not even need a taxi.
The hotel is across the street from Harrah's Casino, and 1 block from the St. Charles Trolley stop, which takes you on the city tour. Also, 1 block from Bourbon Street, 1 block from Mississippi Riverwalk, Paddleboat, & aquarium. It is right between the Garden District & the Warehouse district I'm told.
We chose this hotel because it has a nice pool for the kids, and also not near too much noise at night. Really great price, too. Will try to post back after we go to let you know if it was as great as forecasted.
