I recently stayed at the JW Marriott New Orleans and booked it via Priceline. I lucked out on a good price that was under $80 per night. I booked three rooms and traveled with family members. Upon my arrival it was kind of hectic trying to check in seven people which included three children. The Marriott staff was great and was even able to put two of our rooms together and upgraded the third to a really nice corner room. They got us checked in right away.
The hotel was on Canal St right at St. Charles. I was able to access the Canal Street car or walk around the corner and jump on the St. Charles St. car. I used another members review and ended up parking my car at "Premium Parking" at 716 Iberville right across the street. Print out the coupon for $15 for overnight parking and save big time over the $35 a night that Marriott charges. Premium parking also gives you unlimited in and out privaleges as well. If you plan on riding the street cars check out the Unique Grocery at 127 Royal St. Pick up a three day pass for $12 which is a lot easier tha trying to put together $1.25 every time you want to ride the street cars. Unique Grocery also has great deals on the fermented beverages.
If you want a good choice of a variety of food at a reasonable price jump on the Canal St. car and take it up to Telemachus St and two blocks over at you will arrive at Liuzza's Restaurant (3636 Bienville st). It may look like a hole in the wall but the foot is fantastic. I would try the fried pickles as an appetizer and definitely a frosted schooner of beer. I like the Lasagna and the catfish is also good. However if you plan on walking to the restaurant I would recommend doing so during the daytime hours just based upon the location. If you happen to head over to the garden district I would also recommend going to the Blue Bird Cafe. They have a great breakfast. All in all I had a pleasant experience at the JW and felt the location/service was fantastic!
