We have booked weekend nights through CRO in the middle of a stay twice, and neither time did we have to move. We have done this at OKW in October with a 2-bedroom and SSR in April with a 2-bedroom. We knew there was a possibility of having to move, but were okay with that. They told us at check-in that we would get to keep the same unit the whole time through, and that we just had to go down and swap our keys out twice. An added bonus was that we got mousekeeping for those cash-through-CRO nights.
