I agree with Ellie, cruise ships are marvellous.
When I was in my extremely early twenties, I worked on cruise ships for a few years and went round the world 2 or 3 times (albeit on coasts), not something I would have got to do otherwise. Later on in life I had a hankering to take one as a passenger, but The Man was not so keen. He wasn't sure about being 'enclosed' and being
with people he may not like.
Finally persuaded him and we had a ball. It's like being in the finest hotel, although your actual bedroom might be quite basic to suit your budget, but the rest is fab. The standard of food is usually outstanding! And, better than a static holiday, you go to sleep at night and someone changes the scenery for you. You get to go out to a new garden/ location virtually every day. What's not to like?
Yes, it's not really "travelling" but really, how many of us can really say we immerse ourselves in a country's culture for our couple of weeks off away every year? The VFM is absolutely top notch.
