Hello Peter,
Thanks for your question, and please don't worry, I'm happy to answer all of your queries!
At present there are 19 customers booked on the main tour with 12 clients booked currently onto the Yangtze cruise add on.
Ages range from 28 to 77, with the average around 55, with the split being around 60/40 female to male split.
I hope this helps,
Kindest,
Ben
