Noah'smom-
We have stayed many times in Poly LV Conc. and we tip housekeeping and to a lesser degree, the turndown service people. Of course, it is entirely up to you on what you feel comfortable with. I will tip the concierge person who definitely went out of their way this time. I have not tipped the conc. staff before but I'm sure that the Great Tikiman has more detail on that subject and I believe that some people regularly tip the concierge staff. As a side note- Despite tipping housekeeping adequately each day we have NEVER in all our WDW stays had housekeeping do anything more than just clean the room. We are neither bothered nor disappointed by this since we don't expect it. Have a super visit! We just love the Poly!! Susan
