I would expect the Saturday before the Super Bowl will be very crowded. Families who have arrived in Tampa but want something to do the day before the big game. I would think the Monday after the Super Bowl would be much better since the game will last very late and I don't think many people will be bright eyed and perky-tailed to get up and drive over to Orlando for the day.
Using that logic, I would go for the week after the Super Bowl. People will have Super Bowl "hangovers" (not in the literal sense).
