If I would go to Universal Studios/IOA in early March, how necessary are the express passes? What about over the memorial day weekend? I've got my husband to agree to pull the kids from school for a few days to save money and was hoping to just stay at a cheap motel to make it even more appealing to him, but then we wouldn't get express passes. I don't want to be waiting in lines constantly. Are 2 days enough to tour the parks without the passes? Thank you and stay safe these next few days if your there now!!!
