Honestly though, you aren't missing much if you do have all of the content. This is one of those lots I've only used once and even where I did place it I had to scale it back considerably. It's one of those overdone EA designed venues that feels like it was done up to showcase what the premium content can do even if most of us wouldn't want quite so much of it all in once place. Quite a few other premium content venues like the bakery (where customers are supposed to bake their own products upon arrival?) feel like this as well to many of us.
