We are planning on going next weekend, Mar 1-3, doing IOA on Sat and Universal on Sun. I have 2 children, 1 and 3 yoa. We are meeting up with 6 more adults and two more kids, 5 & 6. We love the roller coasters, but I would like a more specific plan of action. I don't know where to hit first or what. Any advice would be grateful.
