The official Disney website has a pretty good inside view of the rooms. There are also other websites that have the actual floor layout and dimensions available. Finally, the rooms at CR are not significantly different than ones we have personally stayed in at the Poly, GF, WL, and BC. We would also think a frequently understaffed check-in crew may not be able to show you a room upon request. We, however, think it doesn't hurt to ask. If you get shown one, awesome. If not, then there are plenty of other resources.
