Ah sorry, I'm still getting used to our booking systems! I enlisted help from Jules so I now have the correct information for you:

28 people are booked on the Japan Revealed tour in May, of them 16 are doing the Hong Kong add-on...then there will also be 9 people flying out from the UK and joining the add-on only.

Hopefully that makes sense, apologies for the confusion!

Thanks,

Vickie
