But that all depends on timing.
In general, that day should be relatively minimal for theme park crowds but the later in the day you get, the more crowds and longer the wait times for your favorite rides will get. Mardi Gras is until March 15 at Universal and crowds are large every day for the Mardi Party. Moreso on Weekends though. Regardless, you should have a great time as long as you you plan ahead.
HAVE FUN
