OK Lets say I book at 11 months out for a week at OKW studio for 80 points. Then decide, " oh it would be nice to stay at vero beach for the last 2 nites (23 points a nite). How does this work. Do I call MS and say I want to change my last to nites to a different resort. Are there any penalties. I do have to wait for the 7 month window to change correct ( OKW home resort). I just want to make sure it can be done and no penalties. Thanks
