I had the most fun checking out Mardi Gras World in New Orleans. If you have someone who has recommended it, listen to them! Except it they tell you it’s still on Algier Island, which it’s not; it moved in the past few years I guess. It’s actually right next to where all of the big cruise ships dock.
Mardi Gras World makes almost all of the floats for the 53 (and counting!!!) Mardi Gras parades in New Orleans as well as those in Universal Studios, Disney, Euro Disney, and (BONUS FACT) The Chick-Fil-A billboard cows! The tour is $20 but it is so worth the money! You get to try on Mardi Gras costumes, check out the artists as they’re actually working, and walk all around their warehouse.
You even get a slice of King Cake (unless you’re rushed to meet the shuttle and your husband is making you hurry of course).
