Does anybody on here quite understand how a CR account plays with the actual process of booking a room on the Caesars website? I find it very interesting that the website hides entire room categories when I'm logged in that are displayed when NOT logged in. At times this makes sense. For example, as a Diamond I'm pretty aware that booking a Deluxe Room at the Rio doesn't matter; I'm going to get something better from the normal sized rooms. So they only show me Deluxe Rooms as a category. At other times it's completely absurd. For example, the "Caesars Suites" portal if you want a special large suite. Whole categories disappear when i log in. In fact, for August 15-20 (dates of my upcoming Vegas trip), only the Hakone Suites at Caesars even show up. There are plenty of rooms at many resorts if I log out. What's really fascinating is pulling up a rate calendar for a specific room type such as Carioca Suite at Rio. If I'm not logged in, the category doesn't display sold out. Log in? Most weekdays are sold out. This all flows from my idle curiosity about the cost of "living it up" room-wise. P.S. Any recent experience of pay-for-upgrades at the Rio?
