We've found one good way to ensure that Mousekeeping arranges your stuffed animals.
Each morning, we put our tip for Mousekeeping in an envelope, and then we put the envelope in the arms of one of the stuffed animals on the bed. When we return to the room in the evening, our stuffed animals are always arranged on the bed or on the window sill. And, many times we've received towel animals, as well.
We've done this at Coronado Springs, Caribbean Beach, POP, and All-star sports. And, it has worked at each one!
We were going to tip anyway, but by putting the tip in the arms (hands, paws, etc.) of the stuffed animals, it seems like the Mousekeeper appreciates that.
Oh, we only bring "Disney" stuffed animals with us. Stitch, Daisy Duck, etc. The "other" stuffed animals are left at home.
