Cruising Easter Sunday 2025 a mistake?

Need some advice. I’ve got a courtesy hold for a great price on a 7 night ocean view balcony on Harmony, but the catch is it departs on April 20, Easter Sunday. It seems kinda late in the year for spring breakers, and I don’t know of any schools that get the week off AFTER Easter. Should we expect there to be tons of kids and families?
