This hotel is in the French Quarter and walking distance to Bourbon street. You can also take the trolley. It is also about 25 minutes from the wedding venue. Just head West :) The link here will give you the $138 p/n rate. The last day to book at this rate is May 25th. If you try to book and there aren't any available rooms, please let me know so that I can contact the hotel to update.

This link is a search of Marriott properties in the French quarter/downtown area. You are free to stay wherever you like. The French quarter is about 25 minutes from the wedding venue.
Hotel
If you want to stay near the venue and away from the ruckus of Nola, this hotel is perfect. Only 12 minutes away from the French Quarter and on 12 minutes from the wedding venue in opposite directions. It's right off of the expressway. I am working on a block rate. The current rate at this time (February) is about $147 p/n.
