Registration Fees GO UP on march 1st so if you want to save $20 sign up now. Also I was able to get a great deal on a rental car by flying into Baltimore. WE are traveling more after the games and i saw rental car rates for 11 days at $1800, then i almost booked at $1000, but found a great deal with Enterprise and am paying less than $500. SO shop around and consider other airports if you are renting a car.
