Mardi Gras - Premier, Ultra, Elite 2021 dates?

[RoperDK]

I'm trying to book Mardi Gras this fall and AVOID these casino cruises.  Been there, done that, way too crowded.  Can anyone post dates for me please?  I have access to Premier dates (I think), but have searched for the others to no avail.

October 9, November 11 and December 11 are all Ultra cruises.

You might want to check with a PVP at Carnival, who could confirm what weeks are not included.  I have had multiple offers for October, November and early December on Mardi Gras, ranging from Premier to Elite.
