That would be too much vacation for me. One thing to consider with these responses is that there are big cultural differences in how much holiday time people get. Europeans generally get a minimum of four weeks off, and frequently more than that. When I lived in a European country I had eight weeks off.

Whereas Americans generally get two or three weeks. I loved having a lot of vacation time, but now that I am in the US I would regard 6 weeks off in 6 months as excessive for a therapist. Continuity is very important to me, and I'm glad my therapist prioritizes it as well.
