I was an early 2019 hire with 1 year worth of company status from 2018 as a cadet which made me 3/36 in my class and I think the top 5 or so numbers in my class has their own rooms. I think it’s just what the hotel had and they happened to be single beds in the room and they were given to the most senior in class.
when I was in atp/ctp I had to share a room and then when we got moved from the Raddison to the scandelwood I had my own room.
