You will want to put together a list beforehand. Disney does not advertise about half of the characters because they are designed as surprises. Those unadvertised characters are also the first to be cut from the party if needed. You can see the full list of regular characters here: 2010 MNSSHP CHARACTERS Mickeyhunter was indicating that White Rabbit is not a regularly appearing character at MNSSHP this year. That doesn't mean he will not appear, he is just not going to appear consistently for every party. Other random characters may include the Tweedles, Rabbit (from Pooh), the Br'er Characters, plus others. For the PP looking for White Rabbit, he appears daily at the Tea Cups, from about park open to early afternoon. It'll be easier to catch him there rather then MNSSHP.
