Many thanks for your explanation.
I am getting a better understanding. All the caches are already 2 - 5km apart from each other. One is too close to an existing cache, and I have removed it from its posted spot.
Being a series, I'm not sure how I can get away from a "cookie cutter description" (which I have seen in other series listings). The series is called "GOLD SERIES", (Gold Spike, The golden Egg, Golden Golf Ball, Gold Nugget) because I have put a "gold" namesake item in each GC, in order to add interest for younger GC'ers.
I also would prefer to keep each cache as an independent, rather than "stage of a multicache", becasue I think that would appeal more to families. I find that kids don't want to spend too much time doing calculations, etc or seeing only coords in a cache. So, should I move the caches further apart?
How long does it take the appeals to go through? And how do I re-establish communications with the reviewer, in order to reconfigure the series to meet his/her requirements? Maybe I am wrong, but I understand that (s)he is awaiting word from the appeals?
