I was there February of 2009 and I don't remember it being that much.... maybe things have changed. I will actually be going in two weeks (I will be at disney world/ downtown disney Jan 19-23) I'll let you know what's there/changed.
I have to say though every time I have been it has definitely worth the money, even if it is 40$. I miss Disney Quest Chicago so bad, it was only ten minutes from home

O and to be clear you are talking about Disney
World (Florida) correct? For those of you who don't know Disney World is in Florida while Disney Land is in California.
