Make sure you have adequate travel cover, remember the story of the pensioner stranded in Mexico because he did not disclose his full medical history and the insurance company voided his claim!
they probably won't refuse to cover them, just put the premium up a bit. We've got an annual policy with Planet Earth, who seem reasonable, except they won't cover my OH for America/Caribbean, so we had to buy a one-trip policy for that when we went to LA a couple off months back (I think it was from Holiday Extras).
Hi Islay.. I had a couple of pre-exsisting conditions.. Gallstones being one of them and we found Direct line were very good and competative.. good luck Mrs C x
