But that is more of a cultural thing. The Roman gods are more strict with their rules and very rarely even visit mortals, only doing so when their intervention is needed. For Jupiter himself to appear in person at Camp Jupiter, it would probably cause a few minds to be blown (literally and figuratively).

On the other hand, Poseidon only appears before Percy once at his birthday party. All the other times, Percy visited him on Olympus, went to his palace under the sea, or contacted him directly by sitting in his throne. The Greek demigods even have field trips to Olympus, so obviously the Greek gods don't go out of their way to see their children, but don't cut all ties like the Romans do. I can't see Camp Jupiter going on a field trip to Olympus for some reason.
