If your kids are little and/or missing school days is not a problem, plan on going to Disneyland during weekdays. This time of year, crowds aren't bad at all during the week (just make sure it is not during a normal school spring vacation week!), and they will get a lot more time on rides and a lot less time standing in line. (I find the place intolerable during the summer, or duing weekends, due to the extremely long waiting time for rides.)
