Golden Entertainment, slot machine owner and operator and owner of PT’s bars, says it will invest $140 million in a large-scale makeover of the Stratosphere resort and tower, which it recently purchased.

Plans call for a renovation of about half the rooms, the addition of a gastro-brewery, new dining options and the conversion of unused areas into meeting space. The project is expected to be completed by 2021. A new players club that will incorporate the PT’s brand is also in the works.

Mandalay Bay has changed its floor-numbering scheme to eliminate the 32nd floor, now infamous as the firing point for the Oct. 1 Strip shooting. Floors 31-34 have been renumbered 56-59. Guests are already confused by the strange numbering system at the hotel that allocates floors 35-39 to the Four Seasons. Floor numbering will now go 1-30, 35-39 (Four Seasons) and 56-63. Interesting, since the hotel is only 43 stories tall.
