Listen to your own instincts. If a small voice is telling you to take more time off, then it is worth listening to. My small voice said 'try and keep everything as normal as possible' - it was good advice for me and I was lucky enough to be able to follow it. A week off after surgery then back to work. Might have been awful advice for someone else. Holidays are a great time to think about longer term plans and possible changes - I made some of mine about 12 months after diagnosis and they were good moves. Cancer has really no redeeming virtues but going through treatment is a sharp reminder that what doesn't kill you makes you strong. You are still you, but tested,tempered and stronger. Best wishes.
