Tuesday, February 13th, 2018 is the date Mardi Gras falls on this upcoming year. You'll be right in the heart of the action at the hotel you've booked. If you can set something up for before that Tuesday, or really before Friday, February 9th you'll likely be straight. The parade calendar can be found
here.
It's not impossible to play during the end of Mardi Gras season. It's just that if there is a parade happening, you can be stuck in traffic for a whole hour trying to get several blocks away.
