Hi Disneyland experts. I'm looking to book a trip for some 10 yr old grandsons. The problem is they can only go during school breaks. I really hate going on super crowded days. So, my question is-- out of all the school break holidays, would MLK January 18-21 be our best bet? Or would their spring break be better, which is April 8-12. thank you in advance for any opinion that can help me make my decision.
