It appears that each of the MyVegas Room Rewards uses its own calendar; even at the same hotel. That was news to me, and figured it's info worthy of sharing. Since all the Room Rewards are cheap enough anyway, I bought all three Room options for Excalibur so I could quickly shop for the best price. I've posted the images below, and dated them; I suspect they will dynamically update as time goes by. Even though there's the hassle of returning what I didn't use, this system is much more convenient than the old posted JPG calendar (which had to be manually updated periodically, and was often at odds with what the phone operator had). Anyways, here's what Excalibur looks like right now.
