I loaded a new world with our server seed. There are 3 Skelly and 4 Cave spider spawners all within range of one another for a huge farm. Farther away there's a Zombie spawner and 2 more cave spider spawners. In a nearby cave there's also a normal spider spawner (far right 1st photo). There are a few geodes nearby as well as a ruined portal and a buried treasure right above it.
Edit: There's also a trial chamber nearby and my BF alerted me that there's another spot with 5 spawners that are all zombie/skelly but we have since lost those coords.
