For example Muscle Beach and the Beach Playground, for instance they were, at the beginning of the game, I think until the April update.
I built some things at Muscle Beach and I would like the Sims to meet there, but to send them there I have to set the lot assignment to the Beach Volleyball Court, the closest place reachable from the map and then send them there manually. But then they always rush back to the place set in the lot assignment
