Looking to be there on the 27/28 of February. Wisdom?

Wondering how busy it is then. Would it be safe to wait and see if express tickets needed? I’m googling my brains out. Once a childhood trip for kids and want to get the best bang for buck. Appreciate any and all advice. Thank you!! Also posted in Island Adventure forums. Hoping to go to a park a day. Mild mobility issue, but desperate to make amazing memories with my loves.
