You cannot link with any CRO rooms, however, that doesn't necessarily mean you'll have to move. You'll have to check in again on the change day but if it's the same category, you likely would not have to move. You just can't guarantee that you won't. IF you have a specialty option like OKW HH category or a BCV 2 queen (among a number of others) then it's very likely, if not guaranteed, you'd have to move. Even if it's a different size (say 1 BR and you have a L/O 2 BR for the rest), you might not have to move. If you're in a situation where you might not have to move, there are ways to minimize the risk.
