I checked in with not too bad a wait -- after realizing that there was indeed a separate, shorter queue for Hilton HHonors members. They initially had me in a double-queen room on the "staff wing," which has certain advantages, but I asked for a single-king, and they moved me to a different wing. They did warn me that they were shifting me to a new wing, and I agreed to it. I hope I haven't destroyed the Hotel Liaison's finely-crafted plans.
