Here is my current list of characters. It is based on who is appearing most often in the parks right now. The rest of the characters are considered "hit or miss", or "rare". I would suggest using this as a core grouping, and be sure to add in several generic pages in case you meet some for the rarer characters. I included a few others in my book that are my favorites. Good luck and have fun with your projects!
