Forever A Princess,
Yes I asked for the upgrade at check in and was offered it for $40 from our Courtyard rate. I had made my room preference request by fax 4 days prior to arrival and they had met all of my requests with no smoking, bunk beds, good view etc. but all of the 7th floor concierge rooms available had drawbacks such as not having bunkbeds or a worse view and they all had the "bad" balconies. Therefore we opted to keep our original assigned room and it was a great decision.
