Easter is my favorite holiday at WDW! All resorts do some type of candy scramble &/or egg hunt. Yc/BC is our favorite. We've stayed there the past 4 years (including 2019) and it is a lot like you described at UO . I know an above poster said they don't have an egg hunt but they do!! At the candy scramble is where they have the special eggs that you get really nice prizes for. Baskets, disney plush, disney toys, etc. Then they have a really cute carnival with all sorts of fun games, it has a different theme every year. There's character meet and greets, the great golden egg hunt, which is a giant scavenger hunt all over the resort with big prizes for the family that finds the golden egg. I highly doubt they'll do much this year but hopefully everything will return in 2022!
We've also stayed at BW, GF, POR and CSR all at Easter and every resort has had fun activities all day. Also you can pay a small fee for a basket and whatever you want to put in it (can be non-disney stuff) and they'll deliver it to your room Easter morning. Its always packaged beautifully and definitely a highlight of the morning.
