Parking at the park is $9.00, as for the hotel, its not a Universal hotel, so I dont know. Mardi Gras is at USF (universal studios) on each Saturday starting I believe Feb. 11th...not sure on the date. Its business as usual upto the time for the parade, then all the rides shut down. Huge parade, then a concert. Lots of food beads and fun throughout the day. The concert is included with your paid admission to the park. There has been no official announcements from Universal yet as to the entertainment, but there are rumors of Kid Rock, George Thorogood, Bonnie Rait and Kool and the Gang. What else do you want to know?
