From what I've heard, it's a staffing issue. They only have enough housekeeping staff to do what they're doing now. They have held job fairs every month (and have another one coming up in early April) focused on housekeeping, and they are offering higher hourly wages, signing bonuses, etc.. It's a tough labor pool right now.
I think they are starting with the deluxe and will expand to moderates and values as they hire more staff over the next few months.
