Easter 2002 will be early which means that more schools will have vacations around two weeks. When Easter is later, the school vacations extend over four weeks.
I will be joining you down in Orlando that week and plan to get past at least part of the crowds by staying at the Hard Rock Hotel (despite my prior rants and statements to the contrary). It seems to me that Easter and Christmas/New Years would be the optimal times to take advantage of Universal Express.
