@camden11: If I were in your position I'd contact the General Manager (not the shift manager) of the hotel directly and see what can be done. I don't think you'll get your iPod back but the hotel might compensate you in another manner. If nothing else, at least the GM gets to hear about it which means something will probably be done.

I once lost a digital camera in a mini hotel which I frequently stayed in and never got it back either. Nowadays I clear out all drawers the night before I leave and put everything on a desk where I can see them to prevent something like this from happening again.
