With kids aged 2-4, you want a property that treats toddlers as actual guests, not afterthoughts. Cinnamon Shore and the JW Marriott Marco Island both nail this: they're built around family sprawl with multiple pools, calm water features toddlers can actually use, and enough space (homes vs. cramped hotel rooms) so nobody goes feral by day three. Skip the theme parks unless you love crowds and meltdowns. Hit the beach, hit the lazy river, move on.
