My manager just got back from Grande Vista. She saved her welcome packet for me to look at. There was a price sheet for cleaning services. If you pay a cash rental rate, you get a "tidy" every day. But, if you are a timeshare owner (or points owner I would assume) you can pay for extra "tidy" cleanings or a full clean. The prices weren't horrible. I think a studio "tidy" which was making the bed with existing linen, replacing towel and loading the dishwasher was about $19 or so. The prices went up from there but even for the 3 bedroom I do not think it was much more than $50. A full cleaning was about double the price of a "tidy" but it was basically the same cleaning the rooms get when you check out, down to scrubbing the floors.
I never expect a cleaning at a timeshare. I do like how Disney gives you new towels and soaps mid week and a full cleaning every 7 days, should you have an extended stay. I rather liked that service as it usually meant we didn't need to wash the towels. Not a big deal. As far as someone cleaning our dirty room while we are there -- we can do that, vacation or not.
