Probably not if the desk clerk gets it right and the romms are readjusted internally.

Never let them adjust your actual reservation, as they may combine your 3 separate days to a single 3 day stay.

One worse, I had booked 3 consecutive separate PointBreaks stays. When the clerk allowed for the last 2 nghts in the original room, I later discovered the "amendment" converted my last 2 stays to the regular 25,000 points per stay as PointBreaks was no longer available after she cancelled those night and re-booked them
