Noooo idea! DH and I are kind of on a budget (my brother also just announced a destination wedding in Mexico next November!) so we are hoping that after the wedding location is set, we can find a hotel in the area by bidding on Priceline
Lots of downtown and french quarter hotels have accepted some pretty low bids. We did the same thing in Europe and got to stay at really nice places for the same price we'd pay for a hostel!
My cousin said her old coworker/friend just moved to N.O. to work at a restaurant... Emerils New Orleans. It looks nice from the website! So she is going to talk to him about it. There is a private room that seats 14 that would work well. At some point she does want to go eat there where he is cooking, so we could maybe make it work for her wedding! But of course, I don't know the location or what it's close to or if the ceremony could be anywhere near!
