Hmmm... That looks like a fair-sized city -- and I have been to a lot of cities in Asia but don't recognise this one. I don't think it's Hong Kong. But there are a lot of large cities in China that I've never seen, so I wonder if it might be one of those. I'm also a bit bemused by what is in the left of the picture: a rollercoaster???
Yep, it's the run-away mine train at a theme park which I visited. Sadly this particular roller coaster was closed for maintenance on the day. It looks like fun, too.
OK, got it. Ocean Park in Hong Kong. Haven't been to that part of HK either. Things about the Disneyland guess didn't quite seem right, looking at Google maps, but I assumed it was just something odd about the angle of the picture that I couldn't quite work out.
