While not everything is perfect at the property and one can argue that excluding all "named" suites from the upgrade pool is a bit too much, on the "lower" end it can be a decidedly good deal. Book a Deluxe room (points or paid) and as AMB get a split level Duplex Suite that would get most folks very excited at other ICs. Now with Diamond breakfast it is kind of a sweet spot in my book if one can do without Club privileges.
