Hi Mad
It's a difficult question. If you're mum is fairly fit I don't think she would have any problem with the walking. Just You holidays are suitable for people of all mobility levels, and we make sure our customers don't have to do more walking than they are comfortable with. However, there might be some steps to climb - up to the Great Wall, for example - and I don't know how she would manage with those.
Also, our China tour has quite a busy schedule and there will be some early mornings, so she might find it rather tiring.
So while I think your mum would enjoy this holiday, I think there are other Just You holidays that your mum would enjoy much more.
Many of our European holidays have a mix of included and optional excursions, so she would be able to pick and choose which excursions she wanted to do. If she found one day a bit tiring, she would be able to relax the following day. If you'd like any suggestions I'll be happy to help.
That said, I haven't taken this tour myself, so maybe some other Community users will have a different opinion.
Kind regards,
Olly, your editor
