We've done Liberty Tree some years ago, and it was fine.
Good, simple food, and lots of it, and decent character interaction. Food is meat, spuds and veg to put it simply, but very nice all the same.
Would I rush back? Not really, but that is more of a reflection of me wanting to try somewhere different, than it being bad.
We've never done CP, but know people who have, and it got a rave review. I'm sure others who have done it will be along shortly.
If you are going for the characters, it's worth bearing in mind which ones attend each venue.
LT = Goofy, Minnie, Chip & Dale
CP = Pooh and friends
