Best New Orleans Bachelor Party Ideas?

There is no better place for a bachelor party than New Orleans.  Adding to Valerie's excellent answer, I think the Royal Sonesta Hotel New Orleans is an excellent hotel.  Although it is on Bourbon Street, it has rooms on the inside courtyard that are very quiet and the lobby seems far removed from the street outside.  Less quiet, but more appropriate for a bachelor party are the balcony rooms on Bourbon Street.  The hotel also has one of the best jazz clubs in the city, Irvin Mayfield's Jazz Playhouse.  It presents top performers in an elegant setting.I would also second Commander's Palace, one of the best in the city and they can easily accommodate a large party.

Hey Nathan

New Orleans will be so fun for a Bachelor party. The French Quarter is where you want to stay, although, may be expensive. Windsor Court Hotel or The Roosevelt New Orleans would be really cool and central places. Great thing about the french quarter is that there are a ton of bars and restaurants you can walk to. When in July are you going? I was actually just told by a friend that a cocktail festival is going on the third weekend (Tales of the Cocktail-http://talesofthecocktail.com/) and it looks fun. 

The Joint has some of the best bbq i've ever had

Commander's Palace has 25 cent martinis during lunch hours. I repeat, 25 cents. 

Obviously Bourbon Street is a must, I personally found it way too crowded but I can definitely see it being fun for a big group. 

Make your way to Frenchmen Street, super hip jazz bars if you're looking for a more mellow night. 

You'll be there in the warmer months so definitely book a Honey Island Swamp tour to go through the bayou and see some gators. 

Have fun!

Gonna be hot in July but not too busy. Find somewhere downtown close to French Quarter if you don't have a vehicle.
