The Royal Academy’s own website doesn’t seem to be working at the moment (Tibetan hackers?), but Goldman Sachs, the corporate sponsor of the show, have a Flash slideshow you can see here which gives an idea of what it’s like.
I found it a bit dull. The exhibition is huge and the quality of the items is obvious, but it seems a bit same-y; and (because it’s all court art?), it’s all rather formal and grand. I also found it surprisingly un-surprising, somehow. I don’t know much about C18th China (anything, really) so I would have expected it to be more interesting just out of novelty value, but somehow it all seemed rather familiar. Perhaps I just haven’t got the enough knowledge to see the subtleties, or perhaps it actually is all a bit repetitive. It might have been a good idea to get the audioguide. These very big exhibitions are always a bit off-putting anyway; if it was a quarter the size, it might have focussed my mind a bit.
