Hi Grannyannie53,
I've just spoken to the lady who makes the decision on tours and she mentioned that the early May departure is due to be reviewed in 3-4 weeks, and at the moment there is a lot of advertising that includes the Inspirational China tour (as it is historically one of our best selling holidays) so there is a chance there may be some last minute bookers to consider on this date.
However, as you are looking at your options I can share with you that there are currently 8 travellers booked on the Treasures of China tour (main and Yangtze add-on) all bookings are for two travellers.
Kindest regards,
Julia
