If you mean UK then I have and still do travel extensively, We pick somewhere we have never been and go there. I will not bore you with the itineraries but take it, it is from Lands end to John O'Groats, that is in or out of reemission for UK.
Overseas, I have been to Spain and the Balearics but I would only do that if in remission, or not on active treatment. Mo and I are hoping to go to Greece when my next course of treatment is finished end of Sep beginning of Oct.
The lad you need to speak to is AndyG (my Hero), trouble is he is probably off in the Med somewhere at the moment:-D .
Kindest regards – vasbyte
