I can't see EC251 applying here, that's one of the disadvantages of using AA on routings.
However usually AA will provide hotel accommodation if that is the cause. You would normally get that via a card issued in MCO airport, it will typically be at a utilitarian level rather than luxurious. AA is responsible for any out of pocket expenses. You may be better looking at your travel insurance policy if you have one. On the other hand AA will rebook fairly freely on any sensible routing, including BA, if that proves necessary, so by all means look at options which suit you the best before approaching AA.
