As locals, we were concerned that this would be more of a history lesson than we cared to take.  Before the tour started, Joel surveyed the group, and I guess he geared his presentation accordingly, so that we weren't bored.  The food was excellent ; places we didn't know existed in such a cavernous property, and will return to again.  The managers at each stop appeared to be happy to have us, and there is no substitute for warmth and hospitality.  Would love to see this extended to other Caesars properties...
