Ah, Spring time is the time my family usually goes to DL the most. I live in oregon, so the spring break is usually the last week of march, and each time we go there seem to be light crowds ( like 20-30 mins on most rides, 40 on big rides) until about 3ish, when the competitions would get over with. many years there are usually cheerleader/dancers (never really payed attention) that would start ariving since they were done with their competitions at that time. And then lines would get outragious until night time, when everyones watching shows and rides are pretty bare. Oh ya, get there early and take advantage of EE, cause we could a lot of rides on in the morning, and then relax until later that day to come back.And the fri/sat/sun are always buisy when we arive. but We always seem to have fun anyway. Hope this helps
Edit: Erm missed out your saying mid april, so mine will be no help lol
