Like many things, this place just doesn't live up to the hype. If you just stumble across it, I'm sure it's fine, but listen to all the rapture here on the DIS and it will be a huge disappointment. When we stayed at the Beach Club, I was convinced we must have been at the wrong place. I mean this most sincerely - it has no atmosphere and is <i>tiny</i>, nothing more than a ... well, I don't even know how to begin to describe it and I genuinely believed it could not possibly be the place everyone raved about. Go with very limited expectations (i.e. you need to understand precisely what it is) and go at a quiet time (not at traditional mealtimes or after IllumiNations) and you'll probably enjoy it.
I don't mean any disrespect to anyone who loves the place, but I suspect those people either found it of their own accord or properly understood what they would encounter.
