For survival it can always work. we have a temporarily one now but if you want you can start on a good ones with a mix between pre-build houses and plots to free build in
Yea that’s what I was thinking.
Honestly, i believe Guests should have access to only /spawn and then a button warp to the Guest SMP and Guest CMP that will be a relativly large area (500X100 maybe?) that will be World Guarded. Then after they get to know everyone they can start to explore the bigger map. This will give them a chance to build, and explore not be completely bored, and they can get to know everyone a bit better.
This is just my suggestion.
