I'll second Crystal Palace. We were there with me, DH and our two older children, and Tigger (and all the characters) were wonderful. We have some great pictures from it.
Definatly Crystal Palace at MK. Tigger is always there for all meals. He is also a regular at 1900 Park Fare's character breakfast, but he usually seems to rotate days with Eeyore so you may or may not see him there. To be safe, I'd stick with Crystal Palace.
