It's probably going to be pretty busy at that time so it depends on how many rides you want to ride and what your standing in line tolerance is. Is it a one time trip or are you planning on going again at some point? Do you want to ride as many rides as possible or are you happy maybe riding two or three and just enjoying the parks. For me, I would never buy the one day one park one they just introduced because I always hop to a different park. We are also not ride centric, we enjoy riding rides but also just enjoy being in the parks. My son has a 3 year old (she has already been 4 times) so they just decide on 2 must do rides in every park and after that, anything else is a bonus. We have been going since he was 3, so standing in line was just what you did back then and we really don't mind.
