Overseas visitors staying during radiation

I thought I'd put my 2 cents in as someone who is going through that stage now.  I finished 6 months of chemo about 7 weeks ago, had a 3 week break and then did 3 weeks of radiation.  There is no way that I would have wanted visitors, no matter how well-behaved and sensitive they were.  After chemo, I felt physically wrung out - the effects don't disappear straight away...actually, I've still got some of it going on 7 weeks later.  Then you've got the running around involved with radiation, even if you sail through it with regards to side effects.  And it's also quite common during this time to suffer from depression and anxiety.  So, I would say, absolutely not to house guests.  If there's no-one else they can stay with then maybe an airbnb would be the answer.  I know it's always hard to say no - growing up, our house was always the place that interstate relatives relied on but sometimes you've just got to be firm.
