How often do you travel to the client site?

Actually, this depends very much on the project. As I personally do a lot of projects with industrial clients, we work on site a lot. In my current project, for example, I usually travel to the client on Monday evening, and I am then on site until Thursday. On my last project, we either met in the office or worked from home. In general, I believe that the insights gained during the pandemic have made us much more flexible and therefore different working models are possible.
