I love both Cp & LTT for dinner. We have planned both for our upcoming trip.
If I had to choose only one I'd go with CP. The buffet offers more options & lots of variety. The LTT is not a buffet. They offer an all you can eat meal served family style..kind of like Thanksgiving food. CP has Pooh & Friends, but if you have to see Mickey then you'd want LTT.
We have found that character interaction at both to be great.
AT CP Tigger bounced all around with my kids & Eeyore spent a long time too.
AT LTT Minnie was all over my DS who was 6 months at the time. He adored here..big smiles!
Either on is great..just depends on who you want to see & if you like buffets.
