Honestly, I know CP gets rave reviews and H&V not so much but I really did not see much of a difference between them. We are not big buffet people anyway so maybe that's why we felt like we did. Both had very average food. We went for the character interaction for DD and I have to say that even that seemed to be lacking. In both places the characters seemed rushed and at both we had one character that never made it around to us and we had to ask at the end of our meal.
If you just want to see the Pooh characters, we actually had better interaction with them at the UK pavillion at EPCOT, but Piglet was not there.
