H&V had Sophia, Doc, Handy Manny, and Jake last time we were there. Not sure about Tusker house except I think Donald is normally there and others from the Fab 5.
Except for Handy Manny all of the other characters at H&V are in the parks to meet. I mention this because we did H&V several years ago before you could meet the characters elsewhere and it was definitely the worst Disney meal we've ever had.
Tusker House however is on the complete opposite side of the spectrum and is the only character meal we continue to go to. The food is creative and delicious and who doesn't love Mickey and pals in their safari gear!
