@thelawdave When I needed it most, I also read @toolbelt 's encouraging experience. Helped me in deciding to proceed with our Disney cruise.
(My wife booked it in July 2024. My SBRT took place April 9-21, following my February 2025 PCa diagnosis Gleason 7 (3+4) positive on 8 of 14 cores.)
I had mucus and blood on my stool, frequent bowel movement on week 3 post-radiation (I suspect because I had no spacer between the prostate & rectum); it cleared on its own (no meds) at the end of week 3 and I had no issues during the cruise on wk 4. I'm now on wk 6.
I wish you & hope you'll have a problem-free procedure.
Best,
