Choosing just the right river for your party is a great starting point. You will also need to recruit suitable helpers like safety boaters, medic, rescue expert, etc. A great deal depends on your run, participants paddling abilities, and your specific skills. Many hands make a light load and that is certainly true when shepherding a bunch paddlers that might not have that much paddling experience. The float plan sets the tone for the trip and is crucial to sucess. Although everyone has a different pace, planning frequent rest stops helps people to stay hydrated and comfortable. Shuttle logistics often need to be well thought out especially when the weather gets colder.

Sorry about the overly extensive coverage of trip planning. I have included all of the trip planning material from my ACA Trip Leaders Assessment class which is targeted to Scout Masters leading trips with children. For a humorous summary, check out the 7 P's.
