First time to New Orleans. Would like to experience Mardi Gras but don't like crowds/drunks/rowdy people in the street. Choices will be either Feb 8-12 or Feb 21-25. I am trying to avoid to be there when all visitors are in before March 4. Not planning to drive & will stay in tourist areas for easy to access public transportation & safer for tourists. Am I able to get cheaper accommodations on these weeks? Any advice on which week should I go? Is it safe to bring my son with me?
