Could I suggest a cruise? Not with the big companies, but I have used Fred Olsen and find them very good. Staff very helpful and pleasant, food good, and opportunities to go ashore at the various places they visit. That way you can at least have a try out without flying, and they do do trips from Liverpool and Newcastle or Rosyth not just Southampton - which if you live further north would mean a hassle travelling down there. If you tried one of the shorter trips , you would be able to see quite quickly if you enjoyed this and might travel further in the future, or it would confirm that it is not for you both and then I think you make other plans. So if you are free to travel whenever , you might have a UK holiday with your husband and accept that he will want to go off abroad, maybe with a friend or on his own. Do you have any friends with a similar situation, where you might go on a trip that suits you whilst your husband goes abroad.
