If you have little ones, another fun 'activity' to do (we do Chef Mickey's on our day off, so we have extra time) is to ride the monorail. The monorail is the one that stops at all the hotels and goes the other direction from the regular T&TC - MK one.
This is also a good opportunity to ask to ride in the front if you have kids who would like to do that. If there is someone in the front, then get off at the next stop and ask again or wait for the next monorail.
We tend to go late in the breakfast (11:20 or so) and it makes for a lazy morning and really turns into lunch for the kids. As the meal ends and people clear out, there are less tables to visit and the characters spend more time with the remaining people. Almost too much so, if that's possible!
