Mardi Gras advice is everywhere. Indeed, there are whole special magazine advertising sections created about this holiday. As far as we are concerned you can't go wrong no matter what you do. Pick a street & dive in. Just be careful.
Carnival season officially begins in early January & ends sometime in February or March with Fat Tuesday or Mardi Gras. Fat Tuesday can take place on any day between February 3rd & March 9th since Mardi Gras is always scheduled 47 days before Easter.
In 2010 Fat Tuesday is on February 16th.
