Didn't see the Regent promotional email (or at least didn't read it), but I have done considerable searching for pictures and video on the Splendor. Here is a link to a video of the various cabins. This may be the same one they sent. 803 starts at 2:45 if you don't want to be bored with other cabins, hallways and stairs.
