V.S.
I'm sure she'll play with both. I practically had a whole doll town complete with ranch, zoo, park, shops, and multiple families. I did focus on my park, zoo, ranch, and mansion more since they had a more personal touch as well as a ton of animals. However, the whole town was personalized and got a lot of usage. Actually, I ended up being a bit of an interior design nut.
We need to get my 4 year-old niece a doll house at some point, I think.
