Hi Jayne,
We try to make a decision as soon as possible as to whether or not a tour will operate. We do try to opearate as many holidays as possible as we certainly don't want our customers to be disappointed. A final decision will be made by the team, at the latest, about 12 weeks before departure.
This 12 weeks provides enough time to obtain the Visa. If Just You are arranging this for you, it takes about 4 weeks for the China visa from when we receive your passport.
To be positive, China is a very popular destination with solo travellers and looking at the dates for this autumn, only one date was cancelled (at a very early stage) for the Inspirational China tour due to major flight changes - an alternative date was put on sale for 2 days later and has been cleared to operate.
Kindest regards,
Julia
