What would you ask the cm for that changes from visit to visit? Example: location and times of characters? Does that change day by day? Is there a daily schedule for parades and things?
WDW publishes a Times Guide every few days or so for each park that lists the time of the parades and the various character greeting times.
It looks like this -
And you can pick one up on your way into each park. If you are staying at a WDW resort hotel, then I think they will also have them available in the lobby.
I hope this helps!
If you are planning resort time you should ask for a listing of what is happening at the resort. Most of them have free activities likes games at the pool, and outdoor movies at night.
If you are looking to meet a specific character, you can check www.characterlocator.com/ for their location and schedule.
A very helpful hint!
