As far as I know you're best bet to see him is at Breakfastsarurus, he's the "for sure" character.
However, we've seen him and Daisy each time we went to Chef Mickey's for dinner, but he's not a "always there" character.
So if you really must see him do breakfast at the AK.
Also check the entertainment/character greetings scheduled for the day at each park, he's been know to turn up at the various parks. We've seen him in several locations in Epcot, the Mexico one was cute, he was all decked out. We've also had luck finding him at MK.
