myVEGAS’s 2 Night Comp Room Rewards come in two different flavors. Everyone who plays should be able to see the seasonal 2 Comp Nights Rewards (like the current 2 Comp Nights: Fall 2017).
If you purchase chips, though, you may be able to get non-seasonal Two Comp Room Nights Rewards (the different spelling is intentional – myVEGAS uses the number 2 for the seasonal Rewards and spells out two for the regular Rewards).
Currently, non-seasonal Two Comp Nights Rewards are available for Excalibur, Luxor, Monte Carlo and New York – New York.
With the exception of the Luxor, the regular Two Comp Room Nights Rewards are cheaper than the seasonal Rewards. The Two Comp Room Nights Rewards do not have their own calendars, but seem to follow the regular Comp Room Rewards calendars.
