Holiday Apple Cider

I asked on the "recipe" section for some ideas for non-alcoholic holiday beverages, and got some good ideas, esp. for mulled cider. In the process, I designed my own, basically apple cider + ginger ale + spices (cinnamon/cloves) and fresh fruits (on hand, apples, pears, lemon slices, cranberries, etc.). I heated it for a few hours in a crock pot  + Yum!
I also added a jigger of rum for those guest who wanted that. Double Yum!
Well, today there was some leftovers, now cold (but mulled/no rum) so I just poured more ginger ale (diet) in it. OMG, the best. It tastes great cold, too!
So I wonder what others have discovered in this cider area??
