@ann210 I would also ask the hospitals for accom options while doing radiation. In Melbourne at Peter Mac you can stay in apartments at the hospital I dont know whats available where you are. The radiation department may be able to have suggestions.
I am not suggesting travel is not doable but rather explore everything. I found only towards the end of treatment that I became very fatigued. I am presuming it will be six weeks and the time will fly. Pity it is so disruptive to your normal routine.
It will work out but lots to do best wishes
