One little tip about the line for Pooh: There is one line for Pooh and the other character who is out with him (Tigger or Eeyore.) So you wait in a fairly long line, and then are first introduced to Pooh, then you continue on to meet the other character. There isn't a way to just meet the 2nd character if you've already met Pooh!
We waited in line 3 times, first at a time when just Pooh was out, not realizing how the line worked. We then went at a time when Tigger was out, but then he left and Eeyore came out. We waited in the long line for Pooh, then as the folks just in front of us were meeting Pooh, we slipped around and got in the line for the 2nd character. We had to go back several more times to meet Tigger, and followed the same Pooh line process.
For some reason, the CMs won't say a definitive time, like "Tigger will be back at 1:30", but every time I noticed, Tigger and Eeyore took turns, and they stay about half an hour. So if you're there near a half-hour, get in line and the 2nd character is likely to change. If it's just past a half-hour, return in half an hour to see Pooh with another character.
