Thanks very much for the comprehensive report, Wilko Pali Sedef!
The OH and I will be travelling SQ for the first time in September in J, so are particularly interested.
You asked for feedback on the caption v. narration - I enjoyed both, and as already commented on, you have a good voice and accent. You could maybe get two videos for the price of one - a shorter, caption-only version, and the full fat narration added version also?
