You are correct, pool view and / or bunkbeds are an extra cost. Years ago, you could get bunkbeds in a standard room but they got really popularas many guests requested them (myself included), so Disney saw a way to make a little extra money and charge for them. Good thing about charging though is you are guaranteed to have them where as before it was a request and you may or may not have gotten them. Pool view has always been a higher priced room though I believe. What we always did was book standard and hope for an upgrade. The view to us isn't that important.
