I have gone to DL on the last two Easter Sundays (2017 and 2018), and both have been fairly reasonable crowds even though we haven’t even arrived until after church. I hesitate to say “low crowds” and get expectations up too high, but they’ve been on the lower side for sure.
That certainly doesn’t guarantee that the same will be true this year, but since the ticket deals are blocked out that weekend, I suspect that at the very least, it won’t be slammed.
We've never been on Easter weekend and are going this year because my son has a 4 day weekend. It's the perfect opportunity to have 3-day park hoppers with Max Pass and only miss one day of school. I figured we'd make the most of however crowded the weekend is. C'est La Vie!
We went last year kind of by accident. We had breakfast reservations at Storytellers, thought it would be fun on Easter as we were on our way home from an evening event the night before in LA going back down to San Diego. I figured we would leave our hotel, go to Easter Breakfast, and then maybe hit the park for a ride or two before it got crazy when everyone got out of church.
We ended up staying until mid afternoon when we had to head home to get stuff done for the coming week. We would have stayed longer if we could, it never got half as bad as I was expecting.
