I want to use my points to stay at a non-DVC WDW resort - I want to pay cash for Sat and Fri nights and use points for Sun thru Thurs nights -- do you do all of this with MS or do you call CRO for the cash nights and MS for the points nights??? Those who have combined cash and points for the same resort stay -- how many of you were able to keep the same room and how many of you had to change rooms?? Thanks much!!
