I stayed at NOLA club level in Aug 2016 for my wife's birthday and ut was amazing. I used my free certificate from credit card to upgrade.
Club level accomodations in this location are definitely a step above compared to Battery park, Pentagon city etc. The food is very good at the club and if they let you stay in the club level room I would say its worth it, if not no.
NOLA has very good food options around and you would be definitely missing if you choose to eat all your food at the club.
