We just purchased the Clubhouse on Sunday! My twins are turning three on the 27th, and my son turns 7 on the 21st. We got it as a birthday gift for my girls, but my son has been playing with it just as much.
FYI - the characters are interactive with the playhouse. It comes with a Mickey who says maybe seven different things?
I purchased it at our local Toys R Us, it was the last one they had in stock. They didn't have any of the other characters, but they did have the phone and the piano.
It's very, very cute. I was worried about the size, but it folds up so it's like a little case. Also, the slide is very hard to put on - but that might just be because I have three "helpers".
Just thought I'd share!
