Now, I've only stayed at two concierges on property, GF RPC and the Poly and the Poly wins hands down. The Poly has MUCH better food, nicer CM's, a nice lounge (though looking down on the GF lobby can't be beat), and a more relaxed atmosphore. I just feel more comfortable there, and the only other concierge on property I have a desire to try is the Beach Club. I stayed at the YC, but the resort wasn't really my cup of tea. Good luck on your decision!!
