This makes A lot of sense since it seemed they only rented out these Sky Suite deluxe rooms to people who needed an additional room when they were using a sky Suite.
My host at Aria had put me up in one of the deluxe rooms a few times over the years since I didn't qualify for a fully comp Sky Suite.
Sounds like a nice little extra $ revenue simce the rooms in the sky Suite section will definitely get more use out of them.
