They did several years ago when I stayed there and they still do for the luau and the breakfast with Lilo and stitch, so I would guess they still do at check in also.
Yes, they still do this. We recieved them over the counter when we checked in. The kids also got some at Ohana's for breakfast and dinner. We were there January 09 (this year).
We did not stay at the Poly, but had breakfast at Kona's in January. There was a CM in the lobby greeting poeple as they came in and he was passing them out.
