We have 3 boys, ages 9, 6, and 3. Going on a 3 day Disney cruise followed by 3 nights at Disney Animal Kingdom lodge. We did all 4 Disney parks last year. Thinking of trying a new one this year. Need opinions. Universal, Islands of Adventure, or SeaWorld?? Or just do a Disney park again?? We will only have time for probably one park this year as we have plans for baseball game on one day.
