Some include cleaning, some do not. We stayed at Vistana Villages last year in a two bedroom for $130 per night. That included daily cleaning, but we booked through Starwood.
We had stayed at the same resort the year before but rented from an owner and cleaning was not included.
This year we are staying at Wyndham Palms and cleaning is an additional fee, which varies by room size (and resort), and we will probably have the condo cleaned twice in the eight days we are there and take out our own trash the other days.
I guess it depends on the resort and how you book it.
