Depending on when you book, there is the chance of a free upgrade to a king room...but you have to ask nicely if any are available. You have to specifically mention it, as CRO will not bring it up if you don't ask. Also, make sure you say "FREE upgrade", otherwise you do risk being charged for a king room. I have been told that people have asked for the free upgrade as late as check-in, and have been lucky enough to get it. PO-R has a limited number of king rooms, and I believe they are all corner rooms. Hope this helps!
