We're going to FL in a couple of weeks, so the Easter Bunny is bringing beach toys and towels, sunscreen, travel toys (we are driving) and stuff like that. The bunny always brings more toys than candy here. Last year, it was a writing/drawing desk for my oldest with all kinds of art stuff, and one big toy (don't remember what) for the younger with lots of little fun toys.
Also, bubbles are a huge hit around here. Bubbles, sidewalk chalk... lots of great things.
How about a kit where they could plant some seeds for the summer? Last year, we got one that was tomato seeds and ds1 loved it all summer long.
