At the first available moment of downtime, head into the bathroom and fashion a miniature piñata out of toiler paper, hand towels, and whatever adhesive material may be available along the way there. Stain portions of it with different colored soaps to provide color. Stow it in your inventory until a later time, as I'm sure it will come in handy as a distraction in the case you want to trick the staff into thinking that there's a roving Mexican loose in the building.
Feeding should probably not be too big of a concern, as bite-marks can be covered up by the required collars and scarves, and the victims simply entranced into forgetting.
