Hi! We were there in February and they don't have any Disney characters - actually they don't even have a restaurant to have a character breakfast in!
There is Shadow, a Golden Retriever, and B'Lou Crabbe who does magic shows and tells stories. They have a store that sells Disney stuff, and Mickey soaps in the rooms - but that's about it. No matter, we fell in love with the place and joined the DVC. Can't wait to go back.
There are no characters at the resort and no character dining as there is not a sit down restaurant at the resort. While it is a Disney resort, the only signs of Disney characters are some hidden Mickey's and the Tigger & Pooh topiary in the front of the lodge. With that being said, HH is a fabulous resort and you get the same quality as any DVC resort at WDW.
