As far as the towel animals go, from my understanding not all houskeepers even know how to make them and tipping is based on thier service not the animals. We only got animals once or twice but when the kids were small they "posed" thier stuffed animals really cute. We had no idea about i at the time and it was a magical suprise for us.
I'll try to dig up some of the photos.
