There’s an interesting way to get to relativistic speeds - to get close enough to a supermassive black hole, steal enough momentum so you get very close to c, then, a subjective week later, you do the same around another black hole in a different galactic core to shed your momentum and get back to a manageable speed. An intergalactic civilisation would use supermassive black holes as train stations.
