Hi Marion,
Please see below for up-to-date information that I have found using our system:
Main tour: 15 travelers, 2 males/13 females (maximum number of travelers: 21)
Hong Kong add-on: 12 travelers, 1 has provisionally booked, 4 males/9 females (maximum number of travelers: 14)
This brings the total number of travelers on this trip to 27, with the maximum number of travelers at 35.
I hope this helps.
Kindest Regards,
Amy
