Bought this set for my 3 yr old daughter. She LOVES it! It took her about 4 hours total to build it but she was so excited about each new phase that she took a day or two to play with it before building the next character's "set." It is now February and she still delights in playing with it every day. She loves how easy it is to "renovate" the set and make the castle a little different each time - although sometimes her little hands need help with that part but the more she plays with it the more she's able to do on her own. Her big doll house gets almost no play time now...we are considering getting rid of it since she really just wants to play with this lego version. We have combined it with the other "swap and play" princess sets to make a giant magical princess world on her floor. I think Lego hit it out of the park this time and I only wish they would do this type of set with other characters like Belle, Snow White, Jasmine, Mulan, etc.....
