Hey Champ,
Although I've never been there, I remember that I had read that the letter "M" in the "M Resort" belongs to the Marnell Family who were the ones who at least owned if not designed the Rio in LV! This may be why you and your wife enjoyed the rooms! I thought that you'd like to know that!
For more information about the Marnell family and the M, check out in the LVA QOD archives the entry from December 3, 2015 that speaks about the history of the M and the Marnell family!
