@HB I had a similar thread up last week.
I go on a long haul holiday exactly 6 weeks to the day of my op. I have my pre-op in 3 weeks so I will ask my surgeon the question. From the digging I have done, I think it depends a lot on your surgeons preference. However, all of the advice I read onanither surgery forum where surgeons answer questions, was anywhere between 2-4 weeks was fine to go in the pool/sea but no direct sunlight.
